Abstract

We report on a simple tunable laser injection-lock scheme for atomic physics experiments. Seed light from an external cavity diode laser is injected into a high-power fiber-pigtailed diode laser via a fiber optic circulator. High-power outputs (up to ∼600 mW) at the injected frequency have been obtained in a single-mode fiber with tuning over a wide wavelength range (∼15 nm). The scheme is simpler and more cost-effective than the traditional scheme of free-space injection-locking.

摘要

我们报道了一种用于原子物理实验的简单可调谐激光注入锁定方案。来自外腔二极管激光器的种子光通过光纤环形器注入到高功率光纤尾纤二极管激光器中。在单模光纤中，已在宽波长范围（约15纳米）内实现调谐，并获得了注入频率下的高功率输出（高达约600毫瓦）。该方案比传统的自由空间注入锁定方案更简单且更具成本效益。
