- Abstract
In this paper, we reported a 1,938 nm Tm:YAP slab laser pumped by two fiber coupled diode lasers, the maximum output power was 48.1 W at the incident pump power of 140 W, corresponding to the optical-to-optical efficiency of 34.4 % and slope efficiency of 43.6 %. The wavelength was selected at 1,938.8 nm by two etalons inserting in the cavity and the laser linewidth was 0.17 nm. The beam quality factors of $$M^{2}$$ were measured to be 3.5, 4.1 and 4.2 at the output power of 10, 25 and 35 W, respectively.
