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.

该提案描述了一个程序，以基于脊 - 波导分布式Bragg反射器半导体激光开发多波长同时发射激光器。 定义此类激光器需要的应用的特定示例是水蒸气的差分吸收远程光学传感。 具有紧密间距窄激光系的多波源源可用于获得详细的吸收曲线，而无需像目前所做的那样打开激光和关闭吸收峰。 该程序旨在研究和开发适合这些类型应用的简单多重波长源。
