Abstract
CdSe single crystal, with the sizes of â¼54â¯mm in diameter and â¼25â¯mm in length, was grown by a high pressure vertical gradient freeze (HPVGF) technique using (0â¯0â¯1)-oriented seed. The CdSe crystal was characterized with transmission spectrophotometer. The transmission spectra showed that the infrared transmission was above 68% and the mean absorption coefficient was 0.041â¯cmâ1 in the range of 2.5-20â¯Î¼m. Using fabricated CdSe crystal with the dimensions of 6â¯mmâ¯Ãâ¯10â¯mmâ¯Ãâ¯44â¯mm, we demonstrated an optical parametric oscillator (OPO) pumped by a 2.05â¯Î¼m Ho:YLF laser at a pulse repetition frequency of 5â¯kHz. Up to 320â¯mW output was obtained at the idler wavelength of 10.20â¯Î¼m with a pump power of 18.06â¯W. 320â¯mW at 10.20â¯Î¼m, to our knowledge, was the highest power obtained with a 2.05â¯Î¼m laser-pumped CdSe OPO.
