Abstract:
Efficient parametric oscillation is obtained in the 8–10-μm range in a LiInS2 crystal pumped by a femtosecond Cr:forsterite laser. The conversion efficiency of 0.8% at a wavelength of 9.5 μm is achieved for the first time. The 75% SHG efficiency for a Cr:forsterite laser in an LBO crystal is also achieved for the first time.
