Integrated Tm:fiber MOPA with polarized output and narrow linewidth with 100 W average power
Abbreviated Journal Title
THULIUM FIBER LASERS; SINGLE-FREQUENCY; AMPLIFIER; Optics
We report on a Tm:fiber master oscillator power amplifier (MOPA) system producing 109 W CW output power, with >15 dB polarization extinction ratio, sub-nm spectral linewidth, and M-2 <1.25. The system consists of polarization maintaining (PM) fiber and PM-fiber components including tapered fiber bundle pump combiners, a single-mode to large mode area mode field adapter, and a fiber-coupled isolator. The laser components ultimately determine the system architecture and the limits of laser performance, particularly considering the immature and rapidly developing state of fiber components in the 2 mu m wavelength regime.
