Abstract
Sum-frequency mixing (ω3=ω1+ω2) of UV laser radiation (λ1=266 nm and 213 nm) and tunable coherent infrared light (λ2=1.2–2.6 μm) in lithium borate (LBO) generates radiation at short wavelengths (λ3=188–242 nm). The UV radiation at λ1 is produced by the fourth and fifth harmonic of a pulsed Nd-YAG laser. The infrared light is generated with an optical parametric oscillator of beta barium borate. The phase-matching angle Φ is measured as function of λ3 and compared with calculated values. For UV laser radiation at shorter wavelengths (173 nm≦λ1≦213 nm) the calculations predict an extension of the tuning range of the sum-frequency generated at λ3 to wavelengths as short as the LBO transmission cutoff at 160 nm.
