研制了一种小型大功率半导体激光器系统。将分布反馈半导体激光器输出的小功率光注入到锥形芯片放大器后实现功率放大， 得到功率大于700 mW，波长连续可调谐范围大于1 nm的输出激光。该激光器系统不但结构紧凑、输出功率稳定，而且操作方便。 该系统可在激光冷却与囚禁、超冷量子气体、量子信息、原子频标及相关空间实验研究中得到应用。

A compact high-power diode laser system was demonstrated and reported. Weak laser beam of a distributed feedback laser was successfully injected into a tapered chip amplifier, from which more than 700 mW laser power was output and a continuous tuning range of 1 nm was achieved. The laser system has a compact structure and stable laser intensity, and it is convenient to operate. It can be used in laser cooling and trapping of neutral atoms, ultracold quantum gases, quantum information, atomic frequency standards, and relative experiments in space.
