Abstract—We present for the first time a highly efficient Ho:YAP laser at 2117.9 nm, which is double-end in-
band pumped by two all-fiber Tm-doped fiber lasers at 1936 and 1948 nm. Using a single 50 mm long Ho:YAP
rod in a simple L-shaped resonator geometry, a maximum laser output power of 10.1 W and a slope efficiency
of 43.6% with respect to the incident pump power are acquired. The Ho:YAP crystals work under room tem-
perature 24C, and without any active thermal management. This experimental results verify the Ho:YAP crys-
tals can be pumped by the versatile laser sources in the 1.9 m regions.
