High-Power Continuous-Wave and Acousto-Optical Q-Switched Ho∶(Sc0.5Y0.5)2SiO5 Laser Pumped by Laser Diode

         

摘要

We experimentally investigate the continuous-wave (cw) and acousto-optical (AO) Q-switched performance of a diode-pumped Ho∶(Sc0.5Y0.5)2SiO5 (Ho∶SYSO) laser.A fiber-coupled laser diode at 1.91 μm is employed as the pump source.The cw Ho∶SYSO laser produces 13.0 W output power at 2097.9nm and 56.0% slope efficiency with respect to the absorbed pump power.In the AO Q-switched regime,at a pulse repetition frequency of 5 kHz,the Ho∶SYSO laser yields 2.1 mJ pulse energy and 21 ns pulse width,resulting in a calculated peak power of 100 kW.In addition,at the maximum output level,the beam quality factor of the Q-switched Ho:SYSO laser is measured to be about 1.6.
