Abstract
This paper investigates the amplified spontaneous emission (ASE) effect in large-size, high-gain Yb:YAG disk lasers and proposes a theoretical model to suppress this effect using a beveled disk crystal. The Monte Carlo ray-tracing method analyzes the escape efficiencies of ASE photons with different escaping paths, revealing the function of the beveled disk crystal in suppressing the ASE effect. The results demonstrate that the beveling angle significantly impacts the escape efficiency and is closely related to the crystal's refractive index. This study provides theoretical support for designing a suitable beveling angle to compromise the ASE effect based on the refractive index of laser crystals and optimize the disk laser system in real-world applications.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
