摘要

在波长为355 nm、重复频率为100 Hz的漩涡脉冲激光的泵浦下，利用β-Ba2BO4（BBO）光参量振荡器（OPO）首次演示了476 nm-525 nm光谱范围内的可调谐蓝绿漩涡激光。在 495 nm 波长处获得了 0.55 mJ 的最大输出信号涡旋脉冲能量，转换效率为 14.2%。通过改变输出镜的曲率半径，说明了信号激光从涡旋光束到高斯光束的转变过程。

Tunable blue-green vortex pulse laser emitting from an optical parametric oscillator

A tunable blue-green vortex laser within a spectrum range of 476 nm–525 nm was firstly demonstrated from a β-Ba₂BO₄ (BBO) optical parametric oscillator (OPO), pumped by 355 nm vortex pulsed laser operating at 100 Hz repetition rate. The maximum output signal vortex pulse energy of 0.55 mJ at 495 nm wavelength was obtained, corresponding to a conversion efficiency of 14.2%. The transformation process of signal laser from a vortex beam to a Gaussian beam was illustrated by changing the curvature radius of the output mirror.

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.
