Ultraviolet Lasers: Pulsed, CW, and Laser Diodes
What are Ultraviolet Lasers?
Ultraviolet lasers (UV lasers) emit UV laser light, typically in the range of 200 nm to 389 nm. UV lasers offer extremely high photon energy, which opens up a wide range of applications that visible and infrared laser sources can’t address. The most common UV laser sources are the third and fourth harmonics on Nd: YAG, providing 355 nm and 266 nm wavelengths, respectively. It’s important to point out that while 355 nm and 266 nm are the most common UV laser wavelengths, several other Nd: YAG lines can be frequency doubled and tripled, producing a large selection of alternate UV wavelengths. To achieve these higher-order harmonics, the electric field density of the laser must be extremely high. As a result, these lasers are primarily available with q-switching capability. Continuous-wave (CW) UV laser diodes are also available at 375 nm, with single-mode and multi-mode beam profiles and free-space or fiber-coupled outputs.
