The signals in an optical parametric oscillator (OPO) build up from quantum noise. In pulsed OPO’s this can lead to fluctuations in such macroscopic signal properties as rise time, pulse energy, frequency spectrum, and transverse profile. The strength of these fluctuations is investigated by use of simulation models that include quantum noise, multiple longitudinal modes, dispersion, birefringence, arbitrary output coupling, and transverse pump profile. The results are compared with results obtained with classical deterministic models to find out how well such models can estimate expectation values of signal observables.
