Abstract

Rovibration absorption lines both of C 12 O and C 13 O are observed simultaneously with the output of a 2 μ m broadband difference frequency generated in a direct-bonded quasi-phase-matched Li Nb O 3 waveguide, which is a 50 mm device with a single quasi-phase-matching period that is operated at a constant temperature. The wavelength conversion efficiency and the difference-frequency generation bandwidth reach 100 % W and 100 nm, respectively. The idler output bandwidth in the 2 μ m region is obtained by group-velocity matching or phase-mismatch minimization when a 0.94 μ m pump laser diode and a 1.55 μ m tunable signal source are used.
