| Abstract: | A loss-noise model of single-mode laser driven by coloured pump noise with single modulation and the quantum noise with cross-correlation between real and imaginary parts are used to describe a single-mode laser system.On the basis of calculating relative fluctuation of its steady-state mean light intensity,the relations between the statistical fluctuation in a single-mode laser sytem and modulation signal are analyzed.The influence of net gain of the system and self-saturation coefficient on the statistical fluctuation of the laser system is discussed. |
| |
| Keywords: | single-mode laser input signal linear approximation relative steady-state mean light fluctuation. |
