Abstract :
A 4 mW tunable C.W. single-frequency operation of a diode laser coupled to an external dispersive cavity has been achieved at 300¿¿ K. With the appearance of low-frequency pulsations (l.f.p.) at the laser output the single-frequency oscillation is eliminated. The l.f.p. give rise to a few longitudinal modes of the external cavity. On the basis of self focusing a model for l.f.p. phenomenon is proposed
