[25a-D215-2] Investigation of Efficient Operations of a Q-switched Ho Laser with an Intracavity Resonantly Pumping Scheme
Keywords:solid-state laser, resonant-pumping, intracavity pumping
An intracavity pumping scheme for an resonantly pumped Ho:YLF laser was proposed. In this pumping scheme, the Ho:YLF laser is end-pumped inside the side-pumped Tm:YLF laser cavity. This laser has several advantages including high cross-relaxation efficiency, efficient Tm-Ho energy transfer, minimal heating, and high beam quality. The side-pumped Tm:YLF laser was developed as a pump source of the Ho:YLF laser. In preliminary experiments, the laser produced an output energy higher than 60 mJ.
