We demonstrate that m -photon resonant absorption ( m =2, 3, …) in a microcavity produce strong photon number squeezing. The dependence of the Fano factor and the mean photon number on the pumping rate, linear damping rate and m -photon decay rate is investigated analytically and numerically. We show the existence of a lower limit equaling 50% of the Fano factor for the radiation field within the cavity in both transient and steady-state cases. This photon-number squeezing is robust against pumping and one-photon dissipation processes.
