Cooling Geometry Dependent Operation Properties in a Diode End-Pumped Monolithic Yb:YAG Laser

다국어 초록 (Multilingual Abstract)

Operation properties, such as output power, beam radius, and crystal temperature rise were investigatedin a diode-pumped edge-cooled monolithic Yb:YAG laser with ~ 4 W pumping level. The output powershowed saturation behavior because of severe temperature rise and poor spatial overlapping between pumpbeam and lasing mode. Face cooling geometry by using a sapphire plate was also investigated. No apparentsaturation behavior in output power was observed due to the reduced temperature rise, which could beattributed to efficient heat removal through the crystal-sapphire interface.
