High power continuous-wave and quasi-continuous-wave operation of diode-pumped Tm:YAG all-solid-state laser oscillator at 2.02 μm
We present a high-power all-solid-state Tm:YAG laser operating at 2.02 μm in both continuous-wave (CW) and quasi-continuous-wave (QCW) regimes. Through rigorous testing of CW laser diodes (LDs) for QCW pulsed operation, the system achieves an average output power of up to 33.97 W at 100 Hz with a pulse width of 670 μs and a beam quality of M2= 8.66. In the CW regime, it delivers a record-high output power of 317.3 W. The beam quality is degraded to be M2= 22.75 due to the severe thermal effects in the crystal. This is the first demonstration of CW and QCW dual-regime operation in a single diode-pumped Tm:YAG laser oscillator. This versatile laser system offers a reliable solution for applications requiring high-power mid-infrared sources.
