AI Article Synopsis
- The paper presents a 5 kHz sub-nanosecond master oscillator power amplifier (MOPA) laser system using an electro-optically Q-switched Nd:YVO laser.
- The system produces a pulse energy of 520 µJ with a pulse width of 900 ps at a frequency of 5 kHz, which is then amplified using two Nd:YVO amplifiers.
- With an absorbed pump energy of 11.0 mJ, the system achieves a pulse energy of 4.2 mJ and a peak power of 4.7 MW, with an optical-to-optical efficiency of 33.5%.
Article Abstract
A 5 kHz sub-nanosecond master oscillator power amplifier (MOPA) laser system was reported in this paper. The master oscillator was an electro-optically Q-switched Nd:YVO laser directly pumped at 879 nm, yielding a pulse energy of 520 µJ and a pulse width of 900 ps at 5 kHz. With two Nd:YVO amplifiers directly pumped at 914 nm, the pulse energy was further scaled up. Under the absorbed pump energy of 11.0 mJ, the pulse energy was amplified to 4.2 mJ, corresponding to a peak power of 4.7 MW. The optical-to-optical efficiency of the amplifiers reached 33.5%.
