Abstract Continuous-wave operation of room-temperature c− and a−cut Ho:YAP lasers resonantly end-pumped by a diode-pumped Tm:YLF laser at 1.91 µm are comparatively investigated. The maximum output powers of 7.8 W at 2103 nm and 6.09 W at 2130 nm for c−cut Ho:YAP crystal are obtained. The maximum output power of 8.78 W at 2119 nm for a−cut Ho:YAlO3 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.
