Abstract

Experimental results on the frequency modulation (FM) and linewidth characteristics of laser diodes in external cavities are presented. The laser is an uncoated 825 nm AlGaAs semiconductor laser diode. The external cavities consist of a 10X, 0.3 NA microscope objective and a diffraction grating. Measurements were made of the FM coefficient and spectral linewidth as a function of external cavity length.
