Optical Parametric Generators and Amplifiers

Abstract

Abstract. Mid-infrared parametric generators and amplifiers in quasi-phase-matched and birefirngence phase-matched nonlinear crystals are reviewed. Broadband mid-infrared generation using collinear and noncollinear parametric interactions is discussed.

Broadband and tunable optical parametric generator for remote detection of gas molecules in the short and mid-infrared

“…(1) when considering continuous (cw), plane wave monochromatic beams, a nondepleted pump, a zero input idler wave (I 1 0 0), and a lossless and nondispersive medium [12,13]. In the limit of high gain, the solution for signal and idler is simplified to [12,13]:…”

“…Using a Taylor series expansion of the phase mismatch (Δk Δ 12 · Δω where Δ 12 1∕ν g1 −1∕ν g2 ) in Eq. (2), one obtains an estimate of the FWHM of the signal and idler spectra [12,13]:…”

“…The propagation of the field envelopes of the pump, idler, and signal waves inside a medium exhibiting second-order nonlinearity such as a PPMgO:LN crystal is described by three coupled nonlinear equations [11,12]:…”
