Abstract

We report on a broadband self-phase-locked operation of a degenerate continuous-wave (cw) optical parametric oscillator (OPO). Pumped at 532 nm in the green, and using a 10-mm-long MgO:PPLN crystal in a fan-out grating design, by controlling the dispersion of the optical cavity, self-phase-locking of the OPO at degeneracy over an extended bandwidth of 3.5 nm is achieved. Phase-locking is validated by radio frequency and f-2f interferometric measurements. Under self-phase-locking, the OPO exhibits improved overall stability, delivering up to 300 mW of output with a passive power stability better than 1.5% rms over 1.8 min, in a Gaussian TEM₀₀ mode profile.

宽带自锁相简并连续波光学参量振荡器。

报道了简并连续波（cw）光参量振荡器（OPO）的宽带自锁相操作。在532 nm的绿色泵浦下，使用10 mm长的MgO:PPLN晶体进行扇出光栅设计，通过控制光腔的色散，实现了OPO在3.5 nm扩展带宽上的简并自锁相。锁相通过射频和f-2f干涉测量验证。在自锁相模式下，OPO表现出更好的整体稳定性，在高斯TEM00模式下，在1.8分钟内提供高达300 mW的输出，无源功率稳定性优于1.5% rms。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
