Abstract
Noncollinear difference frequency mixing of dye laser and Nd:YAG second harmonic (fundamental) radiation from a commercial laser system is employed for the generation of 2.7-5.3 μm (1.6-1.7 μm) radiations in a flux-grown KTiOAsO4 crystal. The generated radiation is used to scan the methane absorption in the fundamental (v3) and its first overtone (2v3) band at pressure 90 torr in a laboratory made single pass gas cell of length 33 cm.
