英文摘要：

A high beam quality Tm,Ho：YAP laser pumped by the diode laser is reported.The diode laser with the center wavelength of 793.6 nm is chosen as the pumping source.Moreover,a c-cut Tm,Ho：YAP crystal is used as the laser crystal,and 5 at.% Tm^3＋ and 0.5 at.% Ho^3＋ are co-doped in the laser crystal.The liquid nitrogen is used to cool the laser crystal.The parameters of the resonant cavity and the pumping are changed,a 13.1 W output power will be acquired from the Tm,Ho：YAP laser.In addition,the corresponding slope efficiency and the optical-to-optical conversion efficiency of the Tm,Ho：YAP laser are 40.9% and 38.4% respectively.The output wavelength of the Tm,Ho：YAP laser is2 044 nm.The beam quality M^2≈1.1 is obtained from the Tm,Ho：YAP laser by knife-edge method.
