Yb fiber laser pumped mid-IR source based on difference frequency generation and its application to methane detection

A cw narrow-linewidth tunable mid-IR coherent source has become a useful tool for trace gas detection since almost all gases exhibit fundamental rovibrational absorption lines with high absorption strength in the mid-IR. This particular source is obtained by a difference frequency generation (DFG) technique which is that two near- 1R laser pump sources (λ1 λ2) are mixed to generate mid-IR (λ3 = (1/λ1–1/λ2)−1) in a quasi-phase-matched (QPM) nonlinear optical crystal such as a periodically poled LiNbO3 (PPLN) in single-pass geometry.
