Abstract
A high-repetition-rate, high-peak-power 808 nm LD pumped burst mode 1064 nm laser is demonstrated with a YAG/Nd:YAG/Cr4+:YAG composite crystal. A pulse burst energy of 13.2 mJ in a duration of 1 ms is obtained at 31.1 kHz with an optical-to-optical efficiency of 27.2% and a single pulse energy of 425.8 μJ. The pulse width keeps nearly invariable during the pump region and the shortest pulse width is 1.9 ns. The peak power of pulse burst laser reaches 373.7 kW at 10.2 kHz. The beam quality factors of pulse burst laser at 31.1 kHz are measured to be Mx2=1.5 and My2 =1.7 by using the travelling knife-edge method.
