摘要

我们首次在实验中展示了可调谐的正交偏振 Pr3+：LiGdF4 双波长激光器。我们计算了正交偏振双波长增益和损耗与旋转角、Lyot 滤光片和未镀膜玻璃入射角之间的平衡条件。通过调整旋转角、Lyot 滤波器和未镀膜玻璃上的入射角，得到了工作波长为 519.6 和 522.8 nm、604.5 和 607.2 nm 以及 719.2 和 721.5 nm 的连续波（CW）正交偏振双波长激光器。

Tunable Orthogonal Polarized Dual-Wavelength Pr3+: LiGdF4 Lasers in the Visible Range

We experimentally demonstrate for the first time a tunable orthogonal polarized Pr³⁺: LiGdF₄ dual-wavelength laser. We calculate the conditions for balancing the gain and loss of the orthogonal polarization dual-wavelength with the rotation angles, the Lyot filter, and the incident angle on the uncoated glass. By adjusting the rotation angles, the Lyot filter, and the incident angle on the uncoated glass, the continuous-wave (CW) orthogonal polarized dual-wavelength lasers operating at 519.6 and 522.8 nm, 604.5 and 607.2 nm, and 719.2 and 721.5 nm are obtained.
