Abstract

A 671 nm diode laser with a mode-hop-free tuning range of 40 GHz is described. This long tuning range is achieved by simultaneously ramping the external cavity length with the laser injection current. The laser output pointing remains fixed, independent of its frequency because of the cover slip cavity design. This system is simple, economical, robust, and easy to use for spectroscopy, as we demonstrate with lithium vapor and lithium atom beam experiments.

摘要

描述了一种671纳米二极管激光器，其无模式跳变调谐范围为40吉赫兹。通过同时随激光注入电流调节外腔长度来实现这种长调谐范围。由于盖玻片腔设计，激光输出指向保持固定，与其频率无关。该系统简单、经济、坚固，并且易于用于光谱学，正如我们在锂蒸汽和锂原子束实验中所展示的那样。
