Abstract

We report a study of the effect of optical absorption on generation of coherent infrared radiation from mid-IR to THz region from GaSe crystal. The infrared-active modes of ε-GaSe crystal at 236 cm-1 and 214 cm-1 were found to be responsible for the observed optical dispersion and infrared absorption edge. Based upon phase matching characteristics of GaSe for difference-frequency generation (DFG), new Sellmeier equations of GaSe were proposed. The output THz power variation with wavelength can be properly explained with a decrease of parametric gain and the spectral profile of absorption coefficient of GaSe. The adverse effect of infrared absorption on (DFG) process can partially be compensated by doping GaSe crystal with erbium ions.

Type-I DFG output wavelength vs. external PM angle. The filled triangles show the experimental data and solid curve is the fitting curve using the modified Sellmeier equation. Dashed curve: calculated phase matching curve using dispersion of GaSe from Ref. [21]. Dotted curve: calculated phase matching curve using dispersion of GaSe from Ref. [22]. Inset: Measured SHG efficiency of a 3.3-mm long GaSe crystal as a function of the internal pulse energy

(a) Calculated parametric gain (dashed curve) and measured infrared absorption (solid curve) as a function of wavelength. (b) Measured and calculated pulse energies of the DFG generator versus wavelength. Solid squares show the measured infrared pulse energies for pure GaSe, open triangles show the measured infrared pulse energies for Er3+:GaSe, solid curve and dashed curve indicate the calculated pulse energies with and without considering the crystal linear absorption coefficient, respectively. The open circles shown in the THz region are taken from Ref. [8] for comparison.
