Progress of High Power Tm-Doped Fiber Laser
In recent years, Tm-doped fiber laser aroused much attention for its superior properties such as wide tunable range, eye-safe and high nonlinear threshold. Compared with Yb-doped fiber laser, Tm-doped fiber laser is of great advantage in power rising, which has significant application prospects in remote sensing, laser radar, medical care, optical parametric oscillation and other fields. The progress of continuous-wave (CW) and pulsed Tm-doped fiber laser at home and abroad is reported. At present, CW Tm-doped fiber laser has achieved 1 kW output, and single-frequency Tm-doped fiber laser has achieved 608 W output. Moreover, higher laser output will be achieved if high-power high-brightness LD pump source and multi-stage amplifier configuration are used. With Q-switched technology, the repetition rate of pulsed laser achieves 100 kHz, and the single nanosecond pulse energy reaches 360 μJ; with mode-locked technology, the repetition rate of pulsed laser achieves 37 MHz and the average power of the picosecond pulse reaches 3.4 mW. Finally, the trend of Tm-doped fiber laser is discussed.
