Abstract
Mode locking in semiconductor lasers to produce ultrashort continuous optical pulse trains has been investigated by numerous authors. Another aspect of such mode locking is to produce a frequency-modulated (FM) output from a laser, that is, FM-laser oscillations. Such oscillations were first demonstrated in He-Ne1 and then in Nd:YAG lasers.2 With respect to FM-laser oscillation in an external cavity semiconductor laser, an extremely large frequency deviation is feasible because of its wide gain bandwidth.2 On the other hand, direct frequency modulation in a solitary laser diode (LD)3 does not facilitate good use of the full gain bandwidth.
