Gain-switched operation of ultrafast laser inscribed waveguides in Cr:ZnSe
We report the first demonstration of a gain-switched chromium-doped zinc selenide channel waveguide laser. The guided-wave structure was produced by ultrafast laser inscription and exhibited output pulse energies up to 12 µJ . The laser exhibited narrow spectral output with a linewidth less than 1 nm. The beam quality was measured to be M2 = 7 with a highly multimode output profile. The laser had a maximum slope efficiency of 9.8% and no deleterious thermal effects were observed up to an average pump power of 3.3 W.

Abstract

We report the first demonstration of a gain-switched chromium-doped zinc selenide channel waveguide laser. The guided-wave structure was produced by ultrafast laser inscription and exhibited output pulse energies up to 12 µJ . The laser exhibited narrow spectral output with a linewidth less than 1 nm. The beam quality was measured to be M2 = 7 with a highly multimode output profile. The laser had a maximum slope efficiency of 9.8% and no deleterious thermal effects were observed up to an average pump power of 3.3 W.
