Broadband Tunable Infrared Source and its Harmonic Generation
A self-built broadband tunable infrared source is introduced here, and its notable merits are all-optical and high-conversion-efficiency. This infrared source contains an internal signal seed and two noncollinear optical parametric amplifiers. Based on this infrared source, we demonstrate the high harmonic generation from the different atomic and molecular gases using the different driving wavelengths. These results indicate that such system is ideally suited to be used as a tunable source for the laser processing and the physical science.
