ABSTRACT
A diode-pumped wavelength switchable passively Q-switched 2.3â
µm TmYVO4 laser was demonstrated in this work. A CrZnS saturable absorber was introduced into the cavity for initiating passive Q-switching. With the increase of the absorbed pump power, the passively Q-switched laser could be switched from the single wavelength of 2366â
nm to the dual wavelength of 2290 and 2360â
nm. The pulse duration and pulse repetition frequency could be tuned in the ranges of 0.745-1.782â
µs and 2.9-43.4â
kHz, respectively. The pulse energy and peak power were estimated to be 7.5â
µJ and 10â
W, respectively, at an absorbed pump power of 12â
W.
