Difference-frequency generation of fs and ps mid-IR pulses in LiInSe2 based on Yb-fiber laser pump sources

摘要

Difference-frequency generation between signal and idler of Yb-fiber laser synchronously-pumped femtosecond / picosecond OPOs at 53/80 MHz provides maximum single pulse energies exceeding 1 nJ and continuous tuning from 5 µm to 12 µm.
