| Abstract: | We present for the first time a highly efficient Ho:YAP laser at 2117.9 nm, which is double-end inband 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 temperature 24°C, and without any active thermal management. This experimental results
verify the Ho:YAP crystals can be pumped by the versatile laser sources in the 1.9 μm regions. |
