Abstract
High efficient and high power 2 $$\upmu $$ m room temperature Ho:YAG laser resonantly dual-end-pumped by two orthogonally polarized diode-pumped Tm:YLF lasers at 1.91 $$\upmu $$ m was demonstrated. A maximum continuous wave output power of 61.9 W was generated, corresponding to the slope efficiency of 63.9 % with respect to the incident pump power and optical-to-optical conversion efficiency of 59.9 %. At 20 kHz of the pulsed repetition frequency, we achieved a less than 25 ns FWHM pulse, with the maximum output energy per pulse of 2.84 mJ as well as a peak power of approximately 113.6 kW. A beam quality of $$M^{2}<$$ 1.6 was achieved.
