The CO2 laser is the most efficient laser, capable of operating at more than 30% efficiency. That's a lot more efficient than an ordinary incandescent light bulb at producing visible light (about 90% of the output of a lightbulb filament is invisible).

Because of the versatility that comes with multiple wavelengths and nanosecond Q-switched technology, doctors are able to perform a wide range of aesthetic laser treatments, from wrinkle and acne scar reduction, multi-color tattoo removal, pigmented lesion (sun spot) removal, hair removal, and vascular lesion treatments.

The helium gas in the laser tube provides the pumping medium to attain the necessary population inversion for laser action.

The argon ion laser can be operated as a continuous gas laser at about 25 different wavelengths in the visible between 408.9 and 686.1nm, but is best known for its most efficient transitions in the green at 488 nm and 514.5 nm. Operating at much higher powers than the helium-neon gas laser, it is not uncommon to achieve 30 to 100 watts of continuous power using several transitions. This output is produced in a hot plasma and takes extremely high power, typically 9 to 12 kW, so these are large and expensive devices.

Pulsed Nd:YAG lasers are typically operated in the so called Q-switching mode: An optical switch is inserted in the laser cavity waiting for a maximum population inversion in the neodymium ions before it opens. Then the light wave can run through the cavity, depopulating the excited laser medium at maximum population inversion. In this Q-switched mode, output powers of 250 megawatts and pulse durations of 10 to 25 nanoseconds have been achieved.[4] The high-intensity pulses may be efficiently frequency doubled to generate laser light at 532 nm, or higher harmonics at 355 and 266 nm.

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.

Nd:YAG lasers are optically pumped using a flashlamp or laser diodes. They are one of the most common types of laser, and are used for many different applications.

Nd:YAG lasers typically emit light with a wavelength of 1064 nm, in the infrared.[3] However, there are also transitions near 940, 1120, 1320, and 1440 nm. Nd:YAG lasers operate in both pulsed and continuous mode.

One of the excited levels of helium at 20.61 eV is very close to a level in neon at 20.66 eV, so close in fact that upon collision of a helium and a neon atom, the energy can be transferred from the helium to the neon atom.

This shows the beams from two helium-neon lasers passing through two lenses arranged in the Galilean telescope geometry. The beams were made visible with a spray can of artificial smoke.

Nd:YAG stands for neodymium-doped yttrium aluminium garnet; Nd:Y3Al5O12. It is a crystal that is used as a lasing medium for solid-state lasers. The Nd:YAG laser at 1064 nm, can be frequency doubled to 532 nm green light.

In cosmetic applications, ND Yag 1064 lasers are used for laser hair removal and the treatment of minor vascular defects such as spider veins on the legs and face, treament of wrinkles and skin tightening.

The carbon dioxide gas laser is capable of continuous output powers above 10 kilowatts. It is also capable of extremely high power pulse operation. It exhibits laser action at several infrared frequencies but none in the visible. Operating in a manner similar to the helium-neon laser, it employs an electric discharge for pumping, using a percentage of nitrogen gas as a pumping gas.

Helium-neon lasers are common in the introductory physics laboratories, but they can still be dangerous! According to Garmire, an unfocused 1-mW HeNe laser has a brightness equal to sunshine on a clear day (0.1 watt/cm2) and is just as dangerous to stare at directly.
