Abstract

In this study, a saturable absorber (SA) was prepared by using V4C3Tx 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 V4C3Tx material in the 2 μm wavelength band.
