Mid-infrared picosecond laser source with high average output power exceeding 1 W at 4.5 µm
Abstract
The generation of tunable mid-infrared picosecond laser radiation in the spectral range from 3-5um by nonlinear frequency conversion in PPLN is reported. More than 3W output power at 3 µm and 1.1W at 4.5 µm were achieved.
