Abstract

Idler generation from self-difference frequency mixing of the pump wave near 750 nm and the 1062-nm Nd³⁺ laser emission in the bifunctional laser and nonlinear optical YAl₃(BO₃)₄:Nd³⁺ crystal was shown. The efficiency was 0.37%, and the infrared wavelength was tunable in the 2430–2600-nm range. New Sellmeier formulas that predict phase-matching polar angles for frequency conversion processes involving wavelengths up to 2600 nm were established.
