Abstract
We have studied the quantum-noise properties of a small slow-inversion lase r experimentally and theoretically. As a function of pump rate, the average output intensity shows a sharp threshold, but the intensity fluctuations d o not. Under quite generic conditions the intensity fluctuations of a suffi ciently small slow-inversion laser show highly super-Poissonian statistics (even two times above threshold), due to the very weak damping of the spont aneous-emission-driven relaxation oscillation.
