Abstract

In this study, a saturable absorber (SA) was prepared by using V₄C₃T_x and integrated it into a resonant cavity, successfully operating it in a passively Q-switched (PQS) mode for the first time. Under PQS operation, the laser demonstrated a central wavelength of 1936 nm with a maximum average output power of 450.3 mW, a pulse width of 363.6 ns, and a pulse repetition frequency (PRF) of 98.23 kHz. A 120-min power stability at 450.3 mW test yielded a root mean square (RMS) value of 0.81%, confirming the excellent stability of the laser. In addition, the beam quality factors (M²) were measured to be less than 1.20 at 450.3 mW. These findings indicate the promising application potential of V₄C₃T_x material in the 2 μm wavelength band.

基于V4C3Tx饱和吸收体的Tm:YAP激光器被动调q工作

在本研究中，利用V4C3Tx制备了可饱和吸收体（SA），并将其集成到谐振腔中，首次成功地在被动调q （PQS）模式下工作。在PQS工作下，激光器的中心波长为1936 nm，最大平均输出功率为450.3 mW，脉冲宽度为363.6 ns，脉冲重复频率（PRF）为98.23 kHz。在4500.3 mW的120分钟功率稳定性测试中，均方根（RMS）值为0.81%，证实了激光器的优异稳定性。此外，在450.3 mW时测得的光束质量因子（M²）小于1.20。这些发现表明V4C3Tx材料在2 μm波段具有广阔的应用前景。
