论文摘要
我们报告了500兆瓦在460.86 nm转变中用于激光冷却跨原子的频谱纯激光。为此，我们注入了高功率单模式激光二极管，并带有稳定的扩展腔二极管激光器的光。为了优化和监视从属二极管的注射状态和光谱纯度，我们开发了一种使用单个无源光元件的新技术。窄带干扰滤波器会生成合适的监视信号，而无需任何其他电子设备用于数据的处理。我们的方法大大简化了注射锁定激光二极管的日常操作，并且可以轻松地适应其他感兴趣的波长。
We report on the generation of 500 mW of spectrally pure laser light at the 460.86 nm transition used for laser cooling of strontium atoms. To this end we inject a high power single mode laser diode with light from a stabilized extended cavity diode laser. To optimize and monitor the injection status and the spectral purity of the slave diode we developed a novel technique that uses a single passive optical element. A narrow band interference filter generates a suitable monitoring signal without any additional electronics for post processing of the data. Our method greatly simplifies the daily operation of injection locked laser diodes and can be easily adapted to other wavelengths of interest.
