Abstract :
The photon noise of the injection laser is greater when it is modulated with high-frequency signals than in d.c. operation. With the aid of Langevin-noise sources the spectrum of the intensity fluctuations during the turn-on of the laser is calculated. It is shown that the pulse repetition frequency should be as low as possible.
