On the design of pulsed dye laser amplifiers

We apply a formula for the small signal gain of a dye laser amplifier (obtained and verified in a previous work) to the case of a transverse pumped R6G amplifier. We trace a set of curves as a function of dimensionless parameters which give the gain for any combination of the parameters characterizing the amplifier (dye concentration, active length, etc.). The curves can be applied to design dye laser amplifiers for ultrashort pulses, both with saturated or unsaturated gain. We give numerical examples of the use of those curves that suggest that the new designs would require much lower pumping energies than the previous ones. Similar sets of curves can be easily obtained for other dyes or pumping configurations.
