Experimental Study of Y-Cavity Dual-Wavelength Laser with Wide Tunable Frequency Separation Range
A Y-cavity dual-wavelength laser based on Nd∶?GdVO4 and Nd∶?YVO4 crystals is designed, and the dual-wavelength laser signal with a wide tunable frequency separation range is experimentally realized. By independently adjusting the heat sink temperatures of the two crystals and controlling the temperature difference from -50 °C to 30 °C, the measured dual-wavelength frequency separation increases from 270.13 GHz to 379.75 GHz. Furthermore, the dual-wavelength power balance is realized by adjusting the pump powers of the two crystals. Finally, the dual-wavelength laser signal is obtained, which has a tunable frequency separation range of 266.05?379.75 GHz and an output power of 230 mW.
