Short-pulse oscillator development for the Nd:glass laser-fusion systems

Abstract

This paper describes the development of an actively mode-locked and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> -switched (AMQ) Nd:YAG oscillator system that generates a single pulse at 1.06 μm in the range of 100 ps to 1 ns, with energy of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\sim 250 \mu</tex> J, and with good stability and reliability. A stable single axial mode <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</tex> -switched oscillator is also described that generates a long smooth pulse out of which pulses in the ns range are sliced. Synchronization of these two oscillators is also discussed.
