We report on the generation and experimental demonstration of intracavity type II sum-frequency generation (SFG) in a two chip InGaAs/GaAs vertical external cavity surface emitting laser cavity. The demonstrated two-chip cavity generates two orthogonally polarized, independently tunable, high-intensity intracavity lasing modes at different colors. Using a lithium triborate nonlinear crystal in the common collinear folded cavity region, high output power in the blue-green band is generated. Wavelength tuning with CW output powers in excess of 750 mW is demonstrated. By independent wavelength tuning of each fundamental color, tunable SFG output around 490 nm is reported.
我们报告了在两个 InGaAs/GaAs 垂直外腔面发射激光腔片内产生并实验演示腔内型 II 次和频（SFG）的情况。所展示的两片式腔产生了两个正交偏振、独立可调谐、高强度的腔内激光模式，位于不同颜色。在共线折叠腔区域使用三硼酸锂非线性晶体，可在蓝绿光波段产生高输出功率。演示了 CW 输出功率超过 750 mW 的波长调谐。通过独立调谐每种基色的波长，报告了约 490nm 的可调谐 SFG 输出。
