Properties of diode lasers with intensity noise control.
The effect of the reduction of intensity noise by electronic feedback on the frequency stability of a GaAlAs laser is investigated. Only a small increase (approximately 30%) in stability was observed because the intensity and frequency noise were found to be not completely correlated. The technique described can also be used to estimate the coherence function gamma2 between the various noise properties of the laser's emission without using a correlator.
