List of laser types

This is a list of laser types, their operational wavelengths, and their applications. Thousands of kinds of laser are known, but most of them are used only for specialized research.

                                               

Dye laser

A dye laser is a laser which uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers. The dye rhodamine 6G, for example, can be tuned from 635 nm to 560 nm, and produce pulses as short as 16 femtoseconds. Moreover, the dye can be replaced by another type in order to generate an even broader range of wavelengths with the same l ...

                                               

Gamma-ray laser

A gamma-ray laser, or graser, is a hypothetical device that would produce coherent gamma rays, just as an ordinary laser produces coherent rays of visible light. In his 2003 Nobel lecture, Vitaly Ginzburg cited the gamma-ray laser as one of the thirty most important problems in physics. The effort to construct a practical gamma-ray laser is interdisciplinary, encompassing quantum mechanics, nuclear and optical spectroscopy, chemistry, solid-state physics, and metallurgy - as well as the generation, moderation, and interaction of neutrons - and involves specialized knowledge and research in ...

                                               

Ring laser

Ring lasers are composed of two beams of light of the same polarization traveling in opposite directions in a closed loop. Ring lasers are used most frequently as gyroscopes ring laser gyroscope in moving vessels like cars, ships, planes, and missiles. The worlds largest ring lasers can detect details of the Earths rotation. Such large rings are also capable of extending scientific research in many new directions, including the detection of gravitational waves, Fresnel drag, Lense-Thirring effect, and quantum-electrodynamic effects. In a rotating ring laser gyroscope, the two counter-propa ...

                                               

Tunable laser

A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range. There are many types and categories of tunable lasers. They exist in the gas, liquid, and solid state. Among the types of tunable lasers are excimer lasers, gas lasers such as CO 2 and He-Ne lasers, dye lasers liquid and solid state, transition metal solid-state lasers, semiconductor crystal and diode lasers, and free electron lasers. Tunable ...
