Abstract

Solid state regenerative amplifiers have proved to be a reliable source for producing stable millijoule pulses as short as a few picoseconds at repetition rates ranging from a few hertz to several kilohertz. Here we report on the operation of a cw pumped Nd:YLF regenerative amplifier that uses a convex–concave design to optimize output energy and stability while minimizing the energy density on critical intracavity optical components. The amplifier yields stable 5-mJ 40-ps pulses at 700 Hz and has achieved 1-mJ output at a 3.5-kHz repetition rate. Results and analysis of the beam profile and contrast ratio for this system are also presented. Our results are contrasted to the general design considerations of regenerative amplifiers.
