Abstract

In this paper we describe a new technique to improve the performance of Nd:YAG laser-pumped dye laser amplifiers. Such amplifiers exist in many laboratories worldwide and use the commercially available Nd:YAG lasers as pump sources. The technique uses a few beam splitters and mirrors external to the Nd:YAG laser cavity. No modification to the Nd:YAG laser itself is required. Amplified pulses obtained in this way are transform-limited to within a factor of 2.

Typical dye laser pulses after a single stage of amplification. (a) Two typical pulses when the pumping scheme described in this paper was not used. (b) Two typical pulses after one step of decomposition and recombination. A delay of 2.5 nsec is introduced to reduce the effect of the fundamental mode beat of the Nd:YAG laser cavity. (c) Two typical pulses after a second stage of decomposition and recombination is introduced. A delay of 1.25 nsec is introduced to reduce the effect of beats caused by modes that are two intermode spacings apart. (d) Two typical pulses after a third stage of decomposition and recombination is introduced to reduce the effect of beats caused by modes three intermode spacings apart.
