Where there is no external focus adjustment, it may be possible to remove the front bezel and then access an internal focus ring. With luck, it can be turned with a flat blade screwdriver or other suitable tool to tweak for best focus. Take care not to scratch the soft plastic lens. However, it may be necessary to remove a bit of glue locking it in place. If the entire lens assembly is glued - no threaded barrel - adjustment may not be possible.

While it might be feasible to increase the current to the laser diode, unless you know its specifications AND have an accurate laser power meter (mucho $$$), there is no way of knowing when to quit. Above their rated maximum optical power, laser diodes turn into DELDs (Dark Emitting Laser Diodes) or expensive LEDs. Exceed this rating for even a microsecond and your whimpy 3 mW output may be boosted to precisely 0.0 mW 100mw blauw violet lasermodule . This is called Catastrophic Optical Damage (COD) to the microscopic end-facets of the laser diode. There can be also be thermal runaway problems or a combination of both of these depending on design - or lack thereof. However, if you have a bag of these gadgets and are willing to blow a few.

So, if even 5 mW of green isn't bright enough, the optimal solution would be to control the ambient illumination by putting a dimmer on the Sun. :) If this isn't an affordable option, the best that can be done is to use a screen or whatever that is a light color and has a diffuse surface, and orient it to avoid direct Sunlight. Unfortunately, if there is no way to control any of this as would be the case with use by an outdoor tour guide 250mW lasermodule rood , there are no good solutions. Even the best laser pointers have a divergence no better than about 1 milliradian (1 part in 1,000) so the power density of a 5 mW green spot projected on a surface more than a few meters away drops well below that of the 0.5 to 1 mW per square millimeter of Sunlight. Even the pure green color of the laser pointer will be quickly overwhelmed by the ambient illumination.

The following discussion resulted from the claim (mine and others) that reflecting the output of a laser pointer or diode laser module from a mirror might result in a decrease in output if it had optical feedback for power regulation. On one laser pointer I have, there is absolutely no effect rode lasermodule 50mw . On another, output power drops by at least 50 percent. My assumption was that it was the light reflected back and falling on the monitor photodiode that caused the effect and not some weird interference to the lasing process. But given what is described below, I'll concede that in many cases, it may indeed be the latter.

Lens tissue is best, Q-tips (cotton swabs) will work. They should be wet but not dripping. Be gentle - the plastic (probably) or glass and particularly the anti-reflection coating on lens is soft. Wipe in one direction only - do not rub. Also, do not dip the tissue or swab back into the bottle of alcohol after cleaning the optics as this may contaminate it.

Despite their small size and low input power, diode lasers may still represent a significant hazard to vision. This is especially true where the output is collimated and/or invisible (near IR), and/or higher power than the typical 3 to 5 mW. At least you don't have to worry about getting zapped by any high voltage (as in a HeNe or argon laser).

Writeable optical drives (WORM, CD-R) may use IR laser diodes producing 10s of mW. A typical CD-R drive sets the laser power at 3 to 5 mW for read and 25 to 30 mW for write. Various types of laser cameras and laser typesetters may use laser diodes of 100s of mW. These are extremely dangerous even if not that well collimated. Furthermore, since they also use near-IR wavelengths so that there is essentially no warning that a beam is present. In fact groene laserpen 50mW , since the response of the human eye to near-IR radiation results in an weak indication of red light, one may be led to the false conclusion that the output is a weak visible beam when the actual optical power is 10,000 times higher and the damage has already been done.

Laser diodes in the 635 to 650 nm range will be used in the much hyped DVD (Digital Video - or Versatile - Disc) technology, destined to replace CDs and CDROMs in the next few years rode laserpointer 100mw . The shorter wavelength compared to 780 nm is one of several improvements that enable DVDs to store about 8 times (or more - 4 to 5 GB per layer, the specifications allow up to 2 layers on each side of a CD-size disc!) the amount of information or video/audio as CDs (650 MB). A side benefit is that dead DVD players and DVDROM drives (I cannot wait) will yield very nice visible laser diodes for the experimenter. :-)

Visible laser diodes have replaced helium-neon lasers in supermarket checkout UPC scanners and other bar code scanners, laser pointers, patient positioning devices in medicine (i.e., CT and MRI scanners, radiation treatment planning systems), and many other applications groene laserpen 200mW . The first visible laser diodes emitted at a wavelength of around 670 nm in the deep red part of the spectrum. More recently, 650 nm and 635 nm red laser diodes have dropped in price.

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. 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.
