AI Article Synopsis
- The paper discusses a high-performance electro-optical laser system using a YVO4/Nd:GdVO4 composite crystal, pumped by a diode laser at 808 nm.
- It highlights that this composite crystal exhibits a lower temperature distribution compared to similar crystal configurations, which can enhance laser performance.
- Key results include a stable pulse width of 3.8 ns, a repetition rate of 50 kHz, a maximum average output power of 5.6 W, and an impressive slope efficiency of 40.7%, achieving peak power levels of 31.1 kW.
Article Abstract
In this paper, an electro-optical cavity-dumped 1.06 μm laser using YVO4/Nd:GdVO4 composite crystal under 808 nm diode-laser pumping was reported. Theoretical calculations showed that the temperature distribution in YVO4/Nd:GdVO4 crystal was lower than that in GdVO4/Nd:GdVO4 and Nd:GdVO4 crystals under the same conditions. A constant 3.8±0.3 ns pulse width was obtained and the repetition rate could reach up to 50 kHz with a maximum average output power of 5.6 W and slope efficiency of 40.7%, corresponding to a peak power of 31.1 kW.

An electro-optical Q-switched RF-excited Z-fold CO(2) waveguide laser was designed, which can output a Q-switched laser and a cavity-dumped laser synchronously. The build-up time method is presented to stabilize the laser frequency. A closed-loop control system was designed to keep the laser oscillating at the peak of the gain curve by measuring the pulse build-up time continuously and controlling the cavity length.
