A High-Peak-Power Mechanically Q-Switched Tb:LiYF<sub>4</sub> Laser in the Green Spectral Region
We report on a mechanically Q-switched Tb:LiYF<sub>4</sub> laser at 544 nm based on an optical chopper. With appropriate chopper settings, 521 μJ, 86 ns green pulses are generated at 1 kHz, corresponding to a peak power of 6.1 kW. To the best of our knowledge, this is the highest peak po...

| Summary: | We report on a mechanically Q-switched Tb:LiYF<sub>4</sub> laser at 544 nm based on an optical chopper. With appropriate chopper settings, 521 μJ, 86 ns green pulses are generated at 1 kHz, corresponding to a peak power of 6.1 kW. To the best of our knowledge, this is the highest peak power generated using Tb:LiYF<sub>4</sub> lasers to date. Numerical simulations are carried out and agree well with the experimental results, which show that the pulse energy can be further scaled to the millijoule level and the peak power to over 10 kW. |
