The Nova laser as a whole was capable of delivering approximately 100 kilojoules of infrared light at 1054 nm, or 40-45 kilojoules of frequency tripled light at 351 nm (the third harmonic of the Nd:Glass fundamental line at 1054 nm) in a pulse duration of about 2 to 4 nanoseconds and thus was capable of producing a UV pulse in the range of 16 ...
The plans called for the installation of two main banks of beamlines, one in the existing Nova beamline room, and the other in the older Shiva building next door, extending through its laser bay and target area into an upgraded Nova target area. The lasers would deliver about 500 TW in a 4 ns pulse.
The Extreme Light Infrastructure (ELI) is a research organization with the world's largest collection of high power-lasers. [1] ELI operates several high-power, high-repetition-rate laser systems which enable the research of physical, chemical, materials, and medical sciences.
The initial laser pulse was provided by a preamplifier module similar to the one from the NIF, the output of which was switched into the main beamline via a mirror and Pockels cell optical switch. To maximize the energy deposited into the beam from the laser glass, optical switches were used to send the beam to mirrors to reflect the light ...
Long-pulse tunable laser oscillator utilizing a multiple-prism beam expander [6] Multiple-prism beam expanders usually deploy two to five prisms to yield large one-dimensional beam expansion factors. Designs applicable to tunable lasers with beam expansion factors of up to 200 have been disclosed in the literature. [ 3 ]
However the section of the big beam pipe is used with a grid system for alignment with a laser, known as the laser pipe. This particular beamline is approximately 3 kilometers long. In particle accelerators the beamline is usually housed in a tunnel and/or underground, cased inside a concrete housing for shielding purposes.
The 10 beam LLNL Nova laser, shortly after its completion in 1984.In the late 1970s and early 1980s the laser energy per pulse delivered to a target using inertial confinement fusion went from a few joules to tens of kilojoules, requiring very large scientific devices for experimentation.
Here, the view of 5 beams of the 10 beam LLNL NOVA laser are shown shortly after the laser's completion in 1984. Laser fusion at this time thus entered the realm of "big science". This is an image of the massive NOVA laser at LLNL taken in 1984. It is used in the article on inertial confinement fusion. I remember this (rather historically ...
