文摘

In this paper, we reported a 1,938聽nm Tm:YAP slab laser pumped by two fiber coupled diode lasers, the maximum output power was 48.1聽W at the incident pump power of 140聽W, corresponding to the optical-to-optical efficiency of 34.4聽% and slope efficiency of 43.6聽%. The wavelength was selected at 1,938.8聽nm by two etalons inserting in the cavity and the laser linewidth was 0.17聽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聽W, respectively.
