分布式布拉格反射器半导体激光器由于其高效率、小尺寸和可调谐性以及集成频率选择元件提供的频率稳定性而非常适合量子技术应用。在这里，我们提出了设计，制造和电光特性的DBR激光器优化锶为基础的量子技术应用在689.449 nm。该器件实现了高达88 mW的光输出功率，是先前报道的四倍，以及0.4 MHz的光谱线宽。
Distributed Bragg Reflector semiconductor lasers are ideally suited for quantum technology applications due to their high efficiency, small footprint, and tunability in combination with the frequency stability provided by an integrated frequency selective element. Here we present the design, fabrication, and electro-optical characterization of DBR lasers optimized for strontium-based quantum technology applications at 689.449 nm. The devices achieved an optical output power of up to 88 mW, four times more than previously reported, as well as a spectral linewidth of 0.4 MHz.
