The Oven Temperature Profile for Phase-Matching in Second-Harmonic Generation: A Theoretical Approach

Year: 2025

Type: article

Abstract: A crucial factor in achieving high efficiency during second-harmonic generation is maintaining a constant temperature along the beam propagation in the nonlinear crystal, despite a significant non-homogeneous heat input through absorption. In this context, we present a theoretical approach to determine the necessary longitudinal oven temperature profile applied to the crystal’s shell surface to ensure a constant temperature at the center along the propagation axis. The approach is validated through simulations for an exemplary case, followed by a discussion of the results.
