Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
The carbon-dioxide laser (CO 2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available.
An atom laser is a coherent state of propagating atoms. They are created out of a Bose–Einstein condensate of atoms that are output coupled using various techniques. Much like an optical laser, an atom laser is a coherent beam that behaves like a wave. There has been some argument that the term "atom laser" is misleading.
Sure, relaxing in bed is all well and good, but there's just something about getting your nails done that puts you in relaxation mode like nothing else. But with so many ways to get our nails done ...
Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient single-transverse mode, and single-longitudinal-mode, emission with laser linewidths as narrow as 350 MHz (approximately 0.0004 nm at a wavelength of 590 nm), in the high-power pulsed regime.
A chemical laser is a laser that obtains its energy from a chemical reaction.Chemical lasers can reach continuous wave output with power reaching to megawatt levels. They are used in industry for cutting and drilling.

Nd:YAG lasers are also used in the non-conventional rapid prototyping process laser engineered net shaping (LENS). Laser peening typically uses a high energy (10 to 40 joule) 10 to 30 nanosecond pulse. The laser beam is focused down to a few millimeters in diameter to deposit gigawatts of power on the surface of a part.
