We report here the latest achievements in the development of high energy high repetition rate nanosecond lasers along with our roadmap to kJ level with high repetition rate.
Amplitude developed few years ago a high-power nanosecond amplifier based on Pseudo Active Mirror Disk Amplifier Module (PAMDAM) technology. This technology allows to significantly increase the repetition rate of high energy nanosecond and it has been developed in both ND:YAG (Premiumlite-YAG) and ND:Glass (Premiumlite-Glass) versions. The Premiumlite-Glass laser is capable of delivering up to 250J at 0.1Hz at 1053nm in a single beam and a single pulse. Thanks to a specific front-end, the pulsewidth of this laser can vary from a few ns to 15ns with a high resolution (125 ps) programmable pulse shape that is suitable for Laser Driven Dynamic Shock Compression. In this report we will present some of the lasers that have already been developed, manufactured, and delivered (European Synchrotron Radiation Facility, Los Alamos National laboratory) and the perspective of up-scaling the above-mentioned technology to kJ-class laser through THRILL project [1] using PAMDAM technology with higher diameter disks.
We will continue this presentation by presenting Amplitude latest developments in high-power nanosecond amplifier based on rod technology. The Elite HE laser uses this technology and is capable to deliver more than 145J at 1053nm in a single beam with a lower max rep-rate of 1 shot per minute. The Elite HE laser using pulse-shaped front-end could be an interesting alternative solution for Laser Driven Dynamic Shock Compression.
