High energy 1342 nm electro-optically cavity-dumped laser and picosecond regenerative amplifier

We have demonstrated a high peak power electro-optically cavity-dumped (CD) laser and a high energy picosecond regenerative amplifier (RGA) at 1342 nm. Their output power, pulse energy, pulse widths, and peak power were reported, respectively. For CD operation, the maximum pulse energy was 0.308 mJ at 1 kHz with the pulse width of 23.3 ns. The corresponding peak power was 13.2 kW. The maximum pulse energy of 0.243 mJ was extracted from RGA at 1 kHz under the seeded pulse energy of 250 pJ, resulting in its total optical gain of 9.7x10(5). Its pulse width was estimated to be 43.8 ps, corresponding to a peak power of 5.55 MW.
