本文研究了本实验室生长的晶体三硼酸锂（LiB_3O_5，LBO）的临界和非临界相位匹配二次谐波特性。报道了角调谐临界相位匹配近红外辐射的二次谐波产生。在190° C至−3°C的温度范围内实现了1.025至1.253 μm的温度调谐非临界相位匹配二次谐波产生。在1.215 μm处还实现了室温下的光谱调谐非临界相位匹配。获得了大的角度、温度和光谱接受带宽。文中还详细讨论了LBO晶体的生长过程。
The characteristic properties of critically and noncritically phase-matched second-harmonic generation in crystalline lithium triborate (LiB3O5,LBO) grown in our laboratory are investigated. Angle-tuned critically phase-matched second-harmonic generation of near-infrared radiation is reported. Temperature-tuned noncritically phase-matched second-harmonic generation from 1.025 to 1.253 μm was achieved in the temperature range 190° to −3°C. Spectrum-tuned noncritical phase matching at room temperature is also achieved at 1.215 μm. Large angular, temperature, and spectral acceptance bandwidths are obtained. The details of the LBO crystal growth process are also discussed.
