Rayleigh beam
WebIn a propagation treatment at all orders in the pump field and to first order in the probe and signal fields, for a homogeneously broadened line, we obtain three approximation levels for the Rayleigh-type optical mixing signal intensity: the first level is an analytical solution valid only for constant pump intensity; the analytical solution corresponding to the second … WebThe (effective) Rayleigh length is a convenient quantity for calculations in the context of focused laser beams.Essentially, it determines the depth of focus.. When focusing a laser beam into a crystal, e.g. a pump beam into …
