We present an overview of the current state of the literature and research performed by the
authors of the present paper on the experimental and theoretical results on the structural …

Optical transmission range and phase matching (PM) conditions for second harmonic
generation (SHG) of Er^ 3+: YSGG and CO_2 laser in indium doped GaSe: In (0.1, 1.23 …

Abstract Centimeter-sized Te: GaSe (≤ 10 mass%) ingots have been grown by the vertical
Bridgman technique and studied to reveal the potentials for phase matching and frequency …

Ordinary and extraordinary refractive indices of an?-GaSe crystal at terahertz (THz)
frequencies are experimentally determined in this study. Fitting experimental data by THz …

This paper reports high-accuracy Sellmeier and thermo-optic dispersion formulas for GaSe
that provide excellent reproduction of the phase-matching conditions for second-, third-, and …

The optical properties of p-type GaSe and mixed GaSe_1-xS_x, x= 0.04, 0.023, 0.090,
0.133, 0.175, 0.216, 0.256, 0.362, 0.369, and 0.412, crystals were studied to reveal the …

We report a systematic study of AgGaS2-and Al-doped GaSe crystals in comparison with
pure GaSe and S-doped GaSe crystals. AgGaS2-doped GaSe (GaSe: AgGaS2) crystal was …

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 …

The Sellmeier equations for GaS and GaSe are constructed from the nonlinear experiments
thus far reported in the literature. The model calculations based on these equations were …

Nonlinear optical crystals of gallium selenide are efficient up-and downconverters of infrared
and terahertz frequencies. Their nonlinear properties have been investigated at …
