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

We experimentally demonstrate for the first time a tunable orthogonal polarized Pr 3+ : LiGdF 4 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 u...

Description
Summary:We experimentally demonstrate for the first time a tunable orthogonal polarized Pr 3+ : LiGdF 4 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.
