Mid-infrared generation and spectroscopy with a PPLN ridge waveguide
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 leng...
