A set of novel potassium‐calcium‐aluminosilicate glasses are developed to serve as the cladding material for a doped ZnSe core infrared fiber laser. The compositions exhibit high glass transition temperatures between 753°C and 918°C and high thermal expansion coefficients between 5.75 ppm/°C and 8.21 ppm/°C. We demonstrate successful application of these glass compositions as a cladding for a ZnSe tunable fiber laser.

硒化锌可调光纤激光熔覆用铝硅酸盐玻璃

开发了一套新颖的钾钙铝硅酸盐玻璃，用作掺杂的ZnSe芯红外光纤激光器的覆层材料。该组合物表现出在753℃至918℃之间的高玻璃化转变温度和在5.75ppm /℃至8.21ppm /℃之间的高热膨胀系数。我们证明了这些玻璃组合物作为ZnSe可调光纤激光器的包层的成功应用。
