Abstract
Stable and precise pulsations are generated by an AlGaAs self-pulsating laser diode under strong feedback in an external cavity. Self-pulsation frequency dependency versus bias current is reduced from 159 MHz/mA to less than 7 MHz/mA, while the equivalent Q factor of the pulsation, defined in analogy with the Q factor of electrical pulsation, is enhanced by more than an order of magnitude from about 110 to more than 1,750 at 532 MHz.
