提出了一种基于脊波导分布布拉格反射器半导体激光器的多波长同时发射激光器的研制方案。 定义这种激光器的需要的应用的具体示例是水蒸气的差分吸收远程光学感测。 具有紧密间隔的窄激光线的多波长源将有助于获得详细的吸收轮廓，而不必像目前实践的那样打开和关闭激光器的吸收峰。 该计划旨在研究和开发适用于这些类型应用的简单多波长源。
英文摘要
The proposal describes a program to develop multiwavelength, simultaneous emission lasers based on ridge-waveguide distributed Bragg reflector semiconductor laser. The specific example of an application that defines the need of such lasers is the differential absorption remote optical sensing of water vapor. A multiwavelength source with closely spaced narrow laser lines would be useful to obtain the detailed absorption profile without having to turn the laser on and off the absorption peak as is practiced currently. This program is aimed to study and develop a simple multiple wavelength source suitable for these types of applications.
