报道了一种双芯片共线T腔垂直外腔面发射激光器（VECSEL）的设计和实验结果，该激光器能够产生两个连续可调谐的正交偏振激光波长。偏振分束器用于重叠两个VECSEL腔，从而产生理想的II型非线性频率转换的高功率腔内双波长产生。观察到在每个波长处具有超过13 W的组合双波长CW输出功率的几乎相等的功率。在高Q腔中，通过在每个波长独立于其他波长激射的区域中使用双折射滤波器，将波长分离从35 nm调谐到52 nm。
We report the design and experimental results of a two chip co-linear T-cavity vertical external cavity surface emitting laser (VECSEL) capable of generating two continuously tunable orthogonally polarized lasing wavelengths. A polarizing beamsplitter is used to overlap two VECSEL cavities thus generating high-power intra-cavity two-wavelength generation ideal for type-II nonlinear frequency conversion. Nearly equal power at each wavelength with a combined dual-wavelength CW output power in excess of 13 W was observed. In a high Q cavity, the wavelength separation was tuned from 35 nm to 52 nm by using birefringent filters in regions where each wavelength lases independently of the other.
