	Laser construction - Wikipedia, the free encyclopedia
		A helium-neon (HeNe) laser uses an electrical discharge in the helium-neon gas mixture, a Nd:YAG laser uses a light focussed from a Xenon flash lamp, and excimer lasers use a chemical reaction.
		The gain medium is excited by the pump source to produce a population inversion, and it is in the gain medium that spontaneous and stimulated emission of photons takes place, leading to the phenomenon of optical gain, amplification.
		Semiconductor lasers are typically very small, and can be pumped with a simple electric current, enabling them to be used in consumer devices such as compact disc players.

		A laser (light amplification by stimulated emission of radiation) is simply a device that generates a highly concentrated beam of light.
		Infrared lasers use the same 5mW output but they're barely visible or completely invisible to the human eye (680nm and lower), yet they have the ability to travel through, and be effected less, by atmospheric conditions at far greater distances than visible beams.
		GC lasers have all but eliminated the use of transits and other optical instruments that were used to verify grade during the construction process previous to the introduction of lasers.

		A note on the construction of the slit in the diffuse reflector for the waveguides: As can be seen in this photo, the slit where the waveguide resides is somewhat longer than the waveguide itself.
		this is not the optimal dopant concentration for a diode pumped laser, nor for a diode pumped laser with such an inhomogeneous pump profile as a single sided cavity.

	Helium-Neon Laser Construction (Site not responding. Last check: 2007-10-21)
		The most common and inexpensive gas laser, the helium-neon laser is usually constructed to operate in the red at 632.8 nm.
		It can also be constructed to produce laser action in the green at 543.5 nm and in the infrared at 1523 nm.
		The helium gas in the laser tube provides the pumping medium to attain the necessary population inversion for laser action.

	Sam's Laser FAQ - Amateur Laser Construction
		Rather, a laser (or multiple lasers after you are hooked) should be built for the education, challenge, and opportunity for experimentation afforded by dealing with all aspects of laser construction.
		Academic studies in laser physics or related subjects are also not necessary unless you want to attempt to do serious research as all the lasers that can be reasonably constructed at home are based on well established principles where rules-of-thumb and simple calculations will suffice.
		CW argon ion lasers, on the other hand, require huge amounts of current, and the necessary materials to build the tube are not easy to work, toxic, or both (e.g., beryllium oxide, tungsten).

	Sam's Laser FAQ - Amateur Laser Construction
		This either means a laser outputting a polarized beam (by design or see the section: Unrandomizing the Polarization of a Randomly Polarized HeNe Tube) or the use of a polarizing filter on its output.
		Rotate the laser or its polarizer about the axis of the beam until the reflection off the window is minimized (keeping in mind that your actual beam intensity may be varying at the same time if you have a random polarized HeNe tube).
		You have to rip them out of a dead laser of similar size and power, and for HeNe this is a problem as modern sealed HeNe tubes may use at least one mirror that is concave and is only good at the same working distance between the mirrors used in that given tube.
