Subpicosecond Pulse Shape Measurement and Modeling of Passively Mode Locked Dye Lasers Including Saturation and Spatial Hole Burning

We present a theoretical model of the linear and ring, passively mode locked dye lasers. This simple model gives a clear understanding of the role of the amplifier, the absorber, and the dynamics of the degenerate third order nonlinearity resulting from spatial hole burning [1].
