Characterization of Bridgman grown GaSe:Al crystals

Centimeter-sized Al-doped nonlinear GaSe crystals were grown by the modified Bridgman method with heat field rotation. The alumina distribution coefficient in the grown crystals was estimated to be about 8 10 2 for GaSe:Al (0.1 at%) crystals. GaSe:Al (0.5 at%) crystals possess optical properties sui...

Zusammenfassung:Centimeter-sized Al-doped nonlinear GaSe crystals were grown by the modified Bridgman method with heat field rotation. The alumina distribution coefficient in the grown crystals was estimated to be about 8 10 2 for GaSe:Al (0.1 at%) crystals. GaSe:Al (0.5 at%) crystals possess optical properties suitable for non-linear applications. For the first time the increase in the ordinary refractive index of GaSe crystals with doping was demonstrated to be different to other doped GaSe crystals. For the first time the increase in the ordinary refractive index of GaSe:Al was demonstrated.
