| Summary: | A tunable pulsed dual-wavelength laser is presented based on an Nd:YVO<sub>4</sub>/Nd:GdVO<sub>4</sub> combined crystals pair as amplifying medium. By employing pulse width adjustment of an 808 nm laser diode pumping, and a Cr<sup>4+</sup>:YAG crystal for Q-switching, synchronized dual-wavelength laser pulses were obtained at 1063 nm and 1064 nm. Time jitter between the two wavelength pulses is reduced to about 10% of the laser pulse duration. Adjusting the pump beam operation parameters and tuning the crystals pair steady-state temperature between 10 °C and 50 °C, the frequency separation between the dual-wavelength laser pulses gradually decreases from 344.11 GHz to 305.99 GHz. The relative peak powers and the pulses time synchronization remain stable during their frequency separation tuning. |
