Abstract: | We report the difference-frequency generation (DFG) of ultrafast mid-infrared laser radiation around 3???m between two picosecond laser pulses with the center wavelengths of 800?nm and 1064?nm in a MgO:PPLN crystal at room temperature. The two laser pulses were generated from the actively synchronized picoseconds Ti:sapphire and Nd:YVO4 oscillators. We measured the DFG wavelengths tunable from 3.19?C3.29???m and the output power is potential to be several mW. This experiment proves a possible roadmap for ultrafast mid- and far-infrared laser radiation generation and even for the THz radiation. |
