Abstract
We present an efficiency Nd:LiYF4 (Nd:YLF) laser operating at 1313 nm pumped directly into the emitting level 4 F 3/2. At the incident pump power of 10.3 W, as high as 3.1 W of continuous-wave output power at 1313 nm is achieved. The slope efficiency with respect to the incident pump power was 36.1%. To the best of our knowledge, this is the first demonstration of such a laser system. Comparative results obtained for the pump with diode laser at 806 nm, into the highly absorbing 4 F 5/2 level, are given in order to prove the advantages of the 880 nm wavelength pumping.
