View down Nova's laser bay between two banks of beamlines. The blue boxes contain the amplifiers and their flashtube "pumps", the tubes between the banks of amplifiers are the spatial filters. Nova was a high-power laser built at the Lawrence Livermore National Laboratory (LLNL) in California , United States, in 1984 which conducted advanced ...
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.
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 ...
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 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.
Before being used in a beamline endstation, the light is collimated before reaching a monochromator or series of monochromators to get a single and fixed wavelength. During normal operations, the electrons in the storage rings lost energy and as such, the rings were re-injected every 12 (X-ray ring) and 4 (VUV ring) hours.
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 ...
Presumably, the device was named after the multi-armed form of the Hindu god Shiva, due to the laser's multi-beamed structure. Shiva was instrumental in demonstrating a particular problem in compressing targets with lasers, leading to a major new device being constructed to address these problems, the Nova laser.
