Abstract
We report the first cascading third‐harmonic generation by light from an alexandrite laser in β‐BaB2O4. Ultraviolet (UV) light was generated by mixing the fundamental laser light with the second‐harmonic light. The calculated effective nonlinear constant for type I mixing is nearly three times larger than that for type II. Using type I mixing we demonstrated UV light generation in the wavelength region 244–259 nm with 24% mixing efficiency at maximum.Keywords
