| description | A power balanced dual-wavelength laser (DWL) based on the Nd:GdVO<sub>4</sub> crystal is presented. The orthogonally polarized gain spectral evolution of the Nd:GdVO<sub>4</sub> crystal versus the temperature is studied, and the power balancing conditions of the DWLs are theoretically analyzed firstly. In the experiments, by using two output couplers and a temperature controller, the power balanced Nd:GdVO<sub>4</sub> DWL signals at 1063 nm (π) and 1065 nm (σ) are obtained with the crystal heat sink temperature (<italic>T</italic><sub>c</sub>) from 20 °C to 40 °C. The experimental results show, with the pump power at 9.3 W and <italic>T</italic><sub>c</sub> at 25 °C, the DWL signal of the balanced power at 0.78 W for each wavelength and the frequency separation at 0.62 THz is realized. The beam quality M<sup>2</sup> of the π- and σ-polarized DWL signals are measured between 2.1 to 2.4. |
