%X It is proposed and shown theoretically that the physical origin of the excellent mode selectivity and linewidth compressibility but with serious mode instability in the external cavity semiconductor lasers is commonly the drastical decrease of spontaneous emission factor of the external cavity mode relative to that of single F-P cavity mode, which results in decreasing drastically both the gain difference needed for mode selection and the laser phase noise by spontaneous emission determining the spectral linewidth. This may clear up more satisfactorily such a puzzling problem.
