| Abstract: | An efficient and narrow linewidth Cr:ZnSe laser pumped by Tm,Ho:GdVO4 laser with a volume Bragg grating (VBG) is reported. The Cr:ZnSe laser operated at 2580 nm with emitting linewidth (FWHM)
about 0.8 nm. Using the volume Bragg grating, 3.57 W of output was achieved under total incident pump power of 13.1 W, corresponding
to optical-to-optical conversion efficiency of 27.3%. By use of conventional mirror, 4.11 W of output was achieved the same
incident pump power and the optical-to-optical conversion efficiency is 31.4%. |
