Novel Fiber-MOPA based High Power Blue Lasers
A rugged and efficient high power (Watts) blue laser source in the 455470 nm spectral region is proposed. The laser source is capable of cw operation or pulsed operation at multi-kHz or higher repetition rates, as well as capable of RF-modulated-pulse formats. The laser source is based on a novel fiber-amplifier in a master-oscillator-power-amplifier (MOPA)"all-fiber"configuration, and frequency-doubled to the blue spectral region via simple single-pass quasi-phase-matching (QPM) in a nonlinear crystal. Such blue laser sources are ideally suited for underwater imaging and communication in littoral waters, anti-submarine warfare (ASW) communication application in the ocean, specific medical applications, and high-brightness display application.
