Abstract :
We report the measured linewidth of a single-frequency graded-index-rod external-coupled-cavity (GRECC) laser and the linewidth narrowing observed with an added 35 cm external cavity, and the demonstration of an experimental self-heterodyne envelope detection system using a free-running GRECC laser and amplitude modulation.
