High Repetition Frequency Narrow Pulse Electro-Optically Q-Switched Laser for Space Applications

High-power high-repetition-rate Nd:YAG nanosecond slab laser amplifier

“…High power and high repetition rate nanosecond lasers are widely used in laser cleaning, laser ranging, laser processing and other fields [1][2] . Especially in the field of laser cleaning, laser cleaning technology uses short pulse laser to clean the surface of materials quickly, which has a wide application prospect in industrial manufacturing, production and maintenance [3][4][5][6] .…”

High efficiency sub-nanosecond electro–optical Q-switched laser operating at kilohertz repetition frequency*

“…reported a side-pumped EO Q-switched pulse laser with 1-kHz PRF, 1.15-mJ pulse energy, and 1.3-ns PW at the equivalent output transmission of 80% and peak pump power as high as 100 W. [15] In this case, the pump power should be very high, so high that it exceeds the pump threshold and reaches a high gain-to-loss ratio, but high energy consumption and problems such as serious thermal effects of gain medium and thermal induced depolarization of Pockels cell (PC) may take place and need solving. [16,17] Besides the cavity length and OC transmission, the PRF is also an important factor that influences the PWs of lasers.…”
