Abstract

The phase-matching conditions of ${\mathrm{A}\mathrm{g}\mathrm{G}\mathrm{a}\mathrm{G}\mathrm{e}\mathrm{S}}_4$ have been measured for second-harmonic generation at 0.8 and $\text{5.3\hspace{0.17em}μm}$, and difference-frequency generation at 2.2, 3.6–5.1, and $4.8–11.8\text{\hspace{0.17em} μm}$. The improved Sellmeier equations that reproduce well the various phase-matching conditions are presented.
