摘要
Continuous-wave operation of room-temperature c-and a-cut Ho:YAP lasers resonantly end-pumped by a diodepumped Tm:YLF laser at 1.91μm are comparatively investigated.The maximum output powers of 7.8 W at 2103nm and 6.09 W at 2130 nm for c-cut Ho:YAP crystal are obtained.The maximum output power of 8.78 W at 2119nm for a-cut Ho:YAlO_(3)crystal is achieved.The maximum slope efficiency in terms of absorbed pump power approximately reaches 57.8%for c-oriented crystal and about 52.7%for a-oriented crystal.
