Abstract:
The results of theoretical studies are presented, showing that in a BBO crystal in the entire transparency range there are directions with interactions that are not critical in temperature for three-wave processes. All phase-matched processes for frequency conversion (generation of harmonics, sum and difference frequencies, parametric generation) are temperature-critical, but can be realized with a record-high temperature phase-matching width (up to 150 °C·cm).
Keywords:
nonlinear crystal, BBO(β-BaB2O4), frequency conversion, phase matching, temperature width.
