Paper Abstract

Extending the "absolute" current continuous frequency tuning range (without any mode hopping)of a GaAlAs laser diode up to 5A (about one order higher than original) has been obtained with an external cavity constructed by a mirror very close to the facet of the diode. Oscillations of the lasing wavelength around some certain desirable line is also observed when the diode heat sink temperature is increased while keening the injected current constant. These results can be applied to laser diode optical pumning and spectroscopy and it significantly improves the absolute continuous frequency tuning ability of the laser diode.
