Optical harmonics generation and multi-photon absorption, ionization, polymerization or spectroscopy are widely used in practical applications. Generally, the rate of an n-photon effect scales as the n-th order autocorrelation function of the incident light, which is high for light with strong photon-number fluctuations. Therefore `noisy' light sources are much more efficient for multi-photon effects than coherent sources with the same mean power, pulse duration and repetition rate. Here we generate optical harmonics of order 2-4 from","authors_text":"Denis A. Kopylov, Gerd Leuchs, Kirill Yu. Spasibko, Maria V. Chekhova, Tatiana V. Murzina, Victor L.
