Abstract

We firstly demonstrated an obtainable Ho:YAP laser intra-cavity pumped by a diode-pumped Tm:YAP laser. A common 792 nm AlGaAs fiber coupled laser diode was used to pump the a-cut Tm:YAP crystal. In the Tm laser experiment, a maximum output power of 1.9 W at 1958.4 nm was obtained, corresponding to a slope efficiency of 12.1 %. In the Ho laser experiment, a maximum output power of 1.1 W at 2118.2 nm was obtained with a slope efficiency of 8.9% for 21.9 W diode incident pump power on the Tm:YAP crystal. At the maximum output power of the Ho laser, beam quality factor (M²) was measured to be 1.79 and 1.72 in the horizontal and vertical directions, respectively. Further improvement in the performances of the current Ho:YAP laser is predictable via direct producing a more compact gain module by adhesive-free bonding of Ho:YAP to Tm:YAP crystals.
