ABSTRACT:
Semiconductor lasers exhibit transient relaxation oscillation on start-up and specific lasers often exhibit sustained spontaneous pulsations caused probably by crystalline defects. These fluctuations are suppressed in a laser having an integrally formed light emitting diode (LED) which generates spontaneous light which is coupled into the laser by virtue of the close proximity of the laser and the light emitting diode.
