Abstract
A highly accurate gain diagnostic system has been developed which will reliably measure gain coefficients as a function of spatial position and laser transition for specific application to high energy chemical lasers. The system consists of a state-of-the-art single line, single mode, frequency-stabilized DF/HF chemical laser, an advanced programmable optical system which provides a two dimensional raster scan through the lasing medium, and a mini-computer based data processing and control subsystem. The DF/HF chemical laser and scanning optics have been designed for both remote and local operation. The data processing electronics are capable of providing a "quick look" real time gain profile of the medium. The dedicated mini-computer subsystem has been specifically designed to provide a complete analysis of the gain data in both tabular and graphic forms; and, by storing the data as complete digitized waveforms, dramatically reduces the data analysis time compared to conventional techniques. A detailed discussion of the operation and capabilities of the gain diagnostic system will be presented with representative results of the system.
