SHG phase matching in GaSe and mixed GaSe1(1-x)S(x), x < or =0.412, crystals at room temperature.
June 27th, 2008 | by admin |SHG phase matching in GaSe and mixed GaSe1(1-x)S(x), x < or =0.412, crystals at room temperature.
The optical properties of p-type GaSe and mixed GaSe(1-x)S(x), x=0.04, 0.023, 0.090, 0.133, 0.175, 0.216, 0.256, 0.362, 0.369, and 0.412, crystals were studied to reveal the potentials for phase matching and frequency conversion. Comparative experiment on Er3+:YSGG and CO2 laser SHG at identical experimental conditions is carried out at room temperature. Any change in polytype structure of GaSe1(1-x)S(x) was not found.
