Abstract

The optical properties and hardness of GaSe, GaSe:Al, GaSe:S:Al, and GaSe:Al:O crystals are studied to create effective terahertz radiation generators. Doped crystals differ from pure GaSe in high mechanical and optical properties at a optimum doping level. Oxygen doping allows wide ranging changes in birefringence in the terahertz range.

非线性GaSe：Al晶体中的IR至THz下变频

摘要

研究了GaSe，GaSe：Al，GaSe：S：Al和GaSe：Al：O晶体的光学性质和硬度，以创建有效的太赫兹辐射发生器。在最佳掺杂水平下，掺杂晶体与纯GaSe的不同之处在于高机械和光学性能。氧掺杂可以使太赫兹范围内的双折射发生较大范围的变化。
