Mid-infrared generation and spectroscopy with a PPLN ridge waveguide

Abstract:

We have utilised a periodically poled LiNbO3 crystal with a waveguide structure to produce up to 146 μW of mid-IR radiation around 2976 cm-1 by difference frequency mixing of 1064 nm pump radiation with 1558 nm signal radiation. A conversion efficiency of 45%∈W-1 is achieved within a crystal of length 50 mm, and temperature tuning curves are reported. The resultant idler radiation is exploited for high resolution absorption studies of both methane and methanethiol. The absorption cross-sectio...
