Abstract

A three stage Nd:YAG pumped dye laser amplifier chain has been constructed using longitudinal pumping in all three stages. Contrary to common practice, longitudinal pumping is employed to provide high small signal gains ({greater-than or approximate} 105 in a single stage) with better beam homogeneity and easier alignment than transversely pumped systems. A simple mathematical model is described for the gain saturation of picosecond amplifiers which includes the effect of angular hole burning. Experimental results are in good agreement with the model. The theory represents a substantial improvement relative to sampler two level saturation models.
