Year: 2025

Type: article

Abstract: The optical parametric amplification (OPA) characteristics of the novel nonlinear crystal B2GGS are systematically investigated under Type-I phase-matching conditions. By optimizing critical parameters such as wavelength combination, phase-matching angle, non-collinear angles, and crystal lengths, we examine the effects of spatial walk-off and coherence length on OPA performance. The results reveal that non-collinear OPA achieves approximately 1.5 times higher peak gain and broader bandwidth compared to collinear OPA. Furthermore, the coherence length fluctuations with collinear configuration are significantly reduced in non-collinear configuration, enabling more stable and efficient broadband amplification. These findings provide valuable theoretical insights for the design and optimization of high-efficiency, broadband OPA systems, supporting the development of advanced ultrafast laser sources and nonlinear optical applications.
