Titel
Monomode emission with external cavity lasers in the mid-infrared region
Abstract
Monomode operation at 6.6 mu m of an external resonator laser with antireflection -coated PbSe diodes is reported. Changing the angle of the Littrow configuration grating the emission wavenumber was varied over 50 cm(-1) A continuous tuning range of 1.2 cm(-1) was obtained by simultaneous control of the resonator length, grating angle and diode current.
