Paper Abstract

The lasing wavelength shift and mode jumping of a GaAlAs laser diode have been observed by a optical feedback as low as -61dB or even lower (-66dB). The lasing frequency shift and mode jumping occur periodically when the phase of the reflected light changes 22(. This effect already applied into adjusting the diode lasing frequency to the definite line of the atom by simply putting a mirror away from the facet of the diode at a sizable distance nevertheless this atom resonance line is located at the lasing mode hopping region in the case of diode free running.
