Abstract
We report a long-wave infrared source driven by a 1-kHz Yb:YAG thin-disk laser, which comprises two parallel multi-cycle optical parametric chirped-pulse amplifiers (OPCPAs) operating at 2.3 and 3.1 μm, respectively, alongside a stage of ZnGeP2-crystal-based difference-frequency generation (DFG). The resulting 9-μm DFG pulses have an energy of 0.21 mJ, a 3-cycle duration, a 1-kHz repetition rate, and long-term energy stability. The simultaneous output of three synchronized intense lasers at short-wave infrared (2.3 μm), mid-wave infrared (3.1 μm), and long-wave infrared (9 μm), renders the source particularly appealing for multi-color ultrafast applications.
