Small-signal gain and saturation intensity in dye laser amplifiers.
Small-signal gain and saturation intensity are obtained from input and output intensity measurements in a dye amplifier stage in which amplified spontaneous emission changes the amplifier performance. We demonstrate that these measurements lead to more accurate values for the effective gain of the amplifier than what can be obtained from theoretical calculations by using physical parameters of the dye. Furthermore, this method can be used to optimize the power extraction efficiency for a dye amplifier stage transversely pumped by a copper vapor laser.
