AGS/AGSe Crystal
AgGaS2 (AGS) and AgGaSe2 (AGSe) are excellent mid- and far-infrared nonlinear optical crystals. AGS offers good transmission over 0.5–13.2μm, a high nonlinear coefficient and efficient broadband infrared-to-visible conversion at room temperature for infrared detection and ultrafast lasers. AGSe has a broader 0.73–18μm transmission range and a favorable combination of nonlinear coefficient and birefringence, making it a core material for efficient 3–18μm conversion and tunable laser output.
