We present a hybrid microintegrated diode laser module developed for iodine spectroscopy on board a sounding rocket. The laser module is based on a master-oscillator-power-amplifier concept: an extended cavity diode laser serves as the master oscillator, and a ridge-waveguide semiconductor optical amplifier provides the power boost. The module's form factor and mass correspond to 12.5×7.5×2.3 and 750 g, respectively. With an electrical power of 3.75 W supplied to the module, 570 mW of optical power is provided out of a polarization maintaining optical fiber at 1064.490 nm with a technical linewidth of 13 kHz (55 kHz) at a 1 ms (10 ms) time scale. The laser module has successfully passed vibration tests at a level of 8.8 . A nominally identical module has recently been used to demonstrate, for the first time, precision iodine spectroscopy in space.
我们展示了一种为探空火箭上的碘光谱学开发的混合微集成二极管激光模块。该激光模块基于主振荡功率放大概念：一个外腔二极管激光器作为主振荡器，一个脊形波导半导体光放大器提供功率增强。该模块的外形尺寸和质量分别对应于12.5×7.5×2.3和750克。向该模块提供3.75瓦的电功率时，在1064.490纳米处从保偏光纤输出570毫瓦的光功率，在1毫秒（10毫秒）时间尺度下技术线宽为13千赫（55千赫）。该激光模块已成功通过8.8级的振动测试。最近，一个名义上相同的模块首次被用于在太空中演示精密碘光谱学。
