2 μm Q-switched pulses using a double-clad fiber master oscillator power amplifier (MOPA) with high peak power intensity of 3.11 MW/cm2 and pulse energy of 7.9 µJ

This report presents the development and experimental demonstration of a passively high-power Q-switched fiber laser operating at a wavelength of 1940 nm, utilizing MoWS₂ as a saturable absorber (SA). A Q-switched oscillator was constructed using a single-mode thulium-doped fiber (TmDF200) and then to a double-clad thulium-doped fiber (DC-TDF) amplifier stage. The laser system demonstrated in this study showcases a notable average output power of 304 mW, delivering a peak power intensity of 3.11 MW/cm². The pulse energy was 7.96 µJ, while the repetition rate and pulse width were 38.2 kHz and 4.02 µs, respectively. The main amplifier exhibits a commendable slope efficiency of approximately 6.7% and 40 dB signal-to-noise ratio (SNR). The results of this study indicate that MoWS₂ SA can be beneficial for developing robust, stable, high-power Q-switched fiber lasers.
