| Popis: | We report on a laser system based on difference frequency generation (DFG) to produce tunable, narrow-linewidth ( < 30 p m ), and comparatively high-energy mid-IR radiation in the 6.8 µm region. The system exploits a lithium thioindate ( L i I n S 2 ) nonlinear crystal and nanosecond pulses generated by single-frequency Nd:YAG and Cr:forsterite lasers at 1064 and 1262 nm, respectively. Two experimental configurations are used: in the first one, single-pass, the mid-IR energy achieved is 205 µJ. Additional increments, up to 540 µJ, are obtained by performing double-pass through the nonlinear crystal. This laser has been developed for high-resolution photon-hungry spectroscopy in the mid-IR. |
