We demonstrate efficient continuous-wave (CW) and passively Q-switched Tm:LiLuF4 laser operation near 1.9?m.The CW slope efficiency reached 54.8% with respect to absorbed power. Stable passive Q-switching with Cr 2+:ZnS saturable absorbers resulted in minimum pulse duration of 7.6 ns and maximum pulse energy and peak power of 1.26 mJ and 166 kW, respectively.

Abstract
We demonstrate efficient continuous-wave (CW) and passively Q-switched Tm:LiLuF4 laser operation near 1.9?m.The CW slope efficiency reached 54.8% with respect to absorbed power. Stable passive Q-switching with Cr 2+:ZnS saturable absorbers resulted in minimum pulse duration of 7.6 ns and maximum pulse energy and peak power of 1.26 mJ and 166 kW, respectively.File in questo prodotto:
