Tunable Lasers: Generating Wavelengths from the UV Through the IR
Tunable CW ring lasers Ring lasers have been used since the early 1980s to achieve tunable CW radiation from a single longitudinal cavity mode, with spectral bandwidths possible in the kilohertz region.. Similar to their standing-wave counterparts, tunable ring lasers are available that use both dye and Ti:sapphire lasing media..
