Abstract :
A stable narrow spectral linewidth was obtained for an external-cavity laser consisting of an AlGaAs/GaAs distributed-feedback laper and a stabilised electro-optical feedback loop. The linewidth of 500kHz with its fluctuation of less than ±5 kHz was achieved without any temperature control.
