Abstract

We report the realization of a singly resonant optical parametric oscillator (SRO) that is designed to provide narrow-bandwidth, continuously tunable radiation at a wavelength of 1163 nm for optical cooling of osmium ions. The SRO is based on periodically poled, magnesium-oxide-doped lithium niobate and pumped at 532 nm. The output coupling of the resonant idler wave is adjusted to yield up to 400 mW of 1163 nm radiation, with a bandwidth of a few megahertz. For continuous frequency tuning of the idler wave, the SRO is equipped with an intracavity etalon, and the cavity length is controlled with a piezo-actuated mirror synchronized to the etalon angle.

摘要

我们报告了一种单共振光参量振荡器（SRO）的实现，该振荡器旨在提供窄带宽、连续可调谐的辐射，波长为 1163nm，用于锇离子的光学冷却。SRO 基于周期性极化、掺镁氧化锂铌酸锂，用 532nm 泵浦。谐振闲频波的输出耦合被调整以产生高达 400mW 的 1163nm 辐射，带宽为数兆赫。为了连续频率调谐闲频波，SRO 配备了腔内标准具，并且通过与标准具角度同步的压电驱动反射镜控制腔长。
