Investigation of the temporal behavior of the self-Q-switched Ho:GdVO4 laser pumped by a Tm-doped fiber laser

A good beam quality Ho:GdVO4 laser pumped by thulium‐doped fiber laser at 1940 nm

“…At pulse repetition of 10 kHz, the minimum pulse width of 5.8 ns was obtained at 2047.9 nm with the maximum peak power of 177.6 kW, corresponding to the beam quality factor of $${M}_{x}^{2}$$= 1.3 and $${M}_{y}^{2}$$= 1.2. In 2022, Kang et al 25 observed the self‐Q‐switched in Ho:GdVO 4 laser pumped by fiber laser. Self‐Q‐switched phenomenon in Ho:GdVO 4 laser strongly depended on the injection pump power.…”
