Abstract—A c-cut Tm:YAP laser which operated at 1.94 or 1.99 m is reported in detail. The maximum output
power was 20.4 and 19.8 W at the wavelength around 1.99 and 1.94 m, corresponding to the slope efficiency
of 34.3 and 31.5%, respectively. For 1.94 m operation, with an F–P etalon inserted in the cavity, the output
central wavelength was stable around 1.94 m with about 0.15 nm linewidth. The beam quality factor M² was
measured to be ~1.8 for 1.99 m and ~1.9 for 1.94 m.
