For these types of integrated laser diodes, everything takes place inside the chip 700mW laserpen groen . Therefore, the output wavelength is fixed and determined by the properties of the semiconductor material and the device's physical structure. Or, at least that's the way it is supposed to work though with some, reflection of the laser light back into the chip can cause stability problems or even be used to advantage to frequency stabilize the output. There are also tunable diode lasers using external cavity optics to provide a continuous and in some cases, quite wide range of wavelengths without mode hopping. See EOSI's Tunable Laser Diode Systemsfor an example of one commercially available product. You really don't want to ask about the price! :-)

With analog modulation, the output intensity should be related to input voltage between limits. For example, a 0 to 1 V signal may result in an output between that varies between 1 and 10 mW. The limits may be adjustable (gain and offset 200mw laser pointer blauw-violet ). A maximum modulation frequency may be specified but unless the datasheet explicitly lists what this means, it could be at the 3dB point, some other reduction in output amplitude, where the output can no longer swing fully on and fully off, or something else. Where the input is AC coupled, there will also be a lower limit greater than DC/CW.

I have a few laser pens here that go nuts when you aim them at a mirror. With some pointers the mirror has to be precisely aligned much the same as the mirrors at the ends of the laser cavity itself. With others the alignment isn't as critical. These same pens seem to be unaffected by other light sources shining back into the laser including light from another laser pen with the same approximate wavelength.

The same basic comments apply to boosting the output power of expensive green laser pointers (but of course there is much more to lose). The adjustment may vary current or for those that are pulsed (which are most of them), the duty cycle instead. With no thermal management, stability is likely to be significantly worse at higher power even if the laser diode survives. However, since 3 mW and 5 mW pointers may be physically identical inside and out 2000mW laserpen blauw , I don't know whether they are sorted on the basis of power output before labeling or is just a matter of the setting of the power adjust pot - it probably depends on manufacturer/model.

On the other hand, an entire wafer of VCSELs can be tested as a unit with each device evaluated for lasing threshold and power, and beam shape, quality, and stability, It is possible to form millions of VCSELs on a single wafer as a batch process and then test and evaluate the performance of each one automatically. The entire wafer can be burned in to eliminate infant mortalities and assure higher reliability of the final product. Each device can then be packaged or thrown away based on these findings.

Like their IR cousins, the typical maximum power from these devices is around 3 to 5 mW. Cost is in the $10 to $50 for the basic laser diode device - more with optics and drive electronics Ultrafire 16340 CR123 Batterij Lithium Oplaadbare . Higher power types (10s of mW) are also available but expect to spend several hundred dollars for something like a 20 mW module. Very high power diode lasers using arrays of laser diodes or laser diode bars with power output of WATTs or greater may cost 10s of thousands of dollars!

Due to the nature of the emitting junction which results in a wedge shaped beam and unequal divergence (10 x 30 degrees typical), a laser diode is somewhat astigmatic. In effect, the focal length required to collimate the beam in X and Y differs very slightly laserpointer 3000mw groen . Thus, an additional cylindrical lens or a single lens with an astigmatic curvature is required to fully compensate for this characteristic. However, the amount of astigmatism is usually small and can often be ignored. The general beam shape is elliptical or rectangular but this can be circularized by a pair of prisms.

The better way to deal with these laser diodes is to have them already mounted on a heat sink. But now we're talking about $100s for a single unit. But, for a number of reasons, the best type of high power laser diode to get is probably a fiber-coupled module. Then you don't have to mess with beam shape issues, the diode is safely tucked away out of harm, and the fiber output can easily be adapted to your favorite crystal shape laserpen 5000mw groen . Some power is lost in the coupling but it appears as though the specs I've seen are similar for the bare diode assembly and fiber-coupled module. Of course, the cost for such a module now appoaches that of a nicely equipped PC. :)

Low power edge emitting diodes usually operate in a single spatial mode for both axes. Edge emitting diodes more than about 100 mW are almost always multiple spatial mode in the slow (horizontal) axis, single mode in the fast (vertical) axis. Although it may take some effort (see below), a single mode diode can be focused or collimated with diffraction limited performance in both axes. This isn't possible even theoretically for a the slow axis of a multimode diode.

You may have read about truly high power laser diodes - those putting out WATTs, 10s of WATTs, or even 100s of WATTs from a one diode or an array (bar) of diodes in a single package, or multiple laser diode bars. These are usually near-IR emitters, often at 808 nm. Solid State Diode Pumped (DPSS) lasers are driven by these light sources with some providing upwards of 1,000 WATTs (and the upper limit is climbing as you read this). Also see the section: Diode Pumped Solid State Lasers.

If you have your heart set on one of these for your birthday, all I can suggest at the present time is to keep track of what is available surplus and to check with the manufacturers listed in the chapter: Laser and Parts Sources. They do show up on eBay but accuracy of the description and operating conditoin may be unknown. If this is for some sort of academic project with a legitimate research objective 5mW groene laserpen , you may be able to obtain a cosmetic reject or one that doesn't quite meet specs by persistent pleading with one of the laser diode manufacturers. Or, if you can deal with the bare chips, it may be possible to beg a few from one of the companies that produces DPSS laser systems since they use them by the carload, and when purchased by the carload, the cost goes way down.

Most laser diodes up till now (as well as most of those discussed in this document) are edge emitters - the beam exists from the cleaved edge of the processed laser diode chip. These are also called Fabry-Perot (FP) diode lasers since the cavity is essentially similar to that of a conventional gas or solid state laser but formed inside the semiconductor laser diode chip itself 20mw groene laserpointer . The mirrors are either formed by the cleaved edges of the chip or (for high performance types like those that are very stable or tunable) one or both of these are anti-reflection (AR) coated and external mirrors are added.

Apparently, laser diode bars/assemblies of much higher power are now available at roughly equivalent prices if you multiply $10/W by the number of watts (but I don't know for what quantities these prices apply). Check out Industrial Microphotonics Company as one possible supplier. The IMC Products Page lists a wide variety of really interesting items but unfortunately doesn't have any prices 50mw laserpen groen . Bars can be connected in series to ease the power supply requirements enabling them to be driven with lower current at higher voltage (e.g., a 4 bar configuration would use 8 V at 50 A instead of 2 V at 200 A). With individual chips on a common heat sink, this really isn't an option.

Several other companies are developing lasers using a similar approach and systems at many wavelengths - including those in the yellow/orange "no laser land zone" - are now available or will be in the near future.

The cost of Nichia blue/violet laser diodes is high because of their patent monopoly. They patented the C-axis cut of sapphire crystal wafers that is necessary to grow these diodes on. So far the only other material they grow on is silicon carbide, but it doesn't match GaN lattice that well making high power impossible, is much harder than sapphire and adds about 3 to 5 V on top of the 4 to 5 V nitride voltage drop basically cooking the poor little diode. :-(

A typical laser diode is diffraction limited with an emitting area of about 1 um by 3 um. An LED will emit from the surface of its chip over a full hemisphere. In order to radiate over only a limited angle, a lens is added but with idea optics Violet Laser 100mW , the emitting area is still effectively the .3 mm x .3 mm or so area of the LED. This is about 30,000 times that of the laser diode. With the typical 5 mm molded lens, it is more like 1,000,000 times the area. That means the intensity and optical density of the laser diode can be over a million times that of the LED.

This is at low currents, maybe around or possibly under half a milliamp for the usual ones with maximum rated current of 30 mA. These are noticeably nonlinear with efficiency peaking near or maybe under half a milliamp. They are so nonlinear in favor of low currents that they are sometimes referred to as "low current red" and most "low current red" LEDs are these groene laser 50mW . Ones in non-tinted packages often glow orangish or sometimes even yellowish orange at currents that they operate safely at - a secondary spectral band in the yellowish green does not lose efficiency at higher currents the way the main red band does. These LEDs are distinguished by a nominal peak wavelength of 690 to 700 nm.

A commercially-made Schmidt-Cassegrain or Maksutov telescope could project a small spot from an LED at a considerable distance groene laser 200mW . These both use a fairly fast (low f/number) primary mirror and a diverging (negative focal length) secondary mirror to give the net effect of a long focal length slow (f/10 to f/12) optical system. I have a 4 inch diameter SCT with 1.2 m focal length; the 8 inch SCTs are generally 2 m focal length. A 4 inch SCT is pretty small and light weight; 4 inches diameter, maybe a foot long, and a few pounds.

When economical, these shorter wavelength laser diodes will represent the enabling technology for yet another revolution in the storage capacity of optical drives (at least a factor of two better than even DVD). Compared to the 4.5 GB capacity of one surface, one side of a DVD, a DUD (Digital Ultra Disc/k) drive would hold about 13 GB/surface based on the wavelength difference alone (635/400 squared). The developers of the DVD standard have already (as of Spring, 2002) developed a DUD standard so the World will be ready and waiting when the cost of blue-violet laser diodes drops to a reasonable level. As if we need yet another new standard. :)
