A Compact High Efficient Tm:Ylf Laser Dual-End-Pumped By An Equidirectional-Polarizing Fiber Coupled Laser Diode At Room Temperature
OPTIK(2018)
摘要
We report a new compact high efficient CW Tm:YLF laser dual-end-pumped by an equidirectional-polarizing fiber coupled laser diode at room temperature. The maximum output power was 15.2W at 1907.6nm with the incident pump power of 47.4W, corresponding to the optical-to-optical efficiency of 32.1% and the slope efficiency of 37.2%, the beam quality factors were M2 x=3.19 and M2 y=3.29, respectively.
