Intrinsic intensity fluctuations in random lasers
Phys. Rev. A , Volume 74 - Issue Article number: 53808 p. 1- 6
We present a quantitative experimental and theoretical study of shot-to-shot intensity fluctuations in the emitted light of a random laser. A model that clarifies these intrinsic fluctuations is developed. We describe the output versus input power graphs of the random laser with an effective spontaneous emission factor (beta factor).
