Abstract :
Summary form only given. In the present paper, difference-frequency generation of two single-mode diode lasers with powers of 30 and 50 mW in a 32-mm-long AgGaS/sub 2/ crystal with a cut for type I noncritical phase matching at room temperature is applied to get a very compact tunable laser system for the mid-infrared spectral range.
