Abstract
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.
