Livermore Lab's SBC grating optics benefit from the combination of the following key technologies:
LLNL researchers have invented a method for scaling the average power of high-energy solid-state lasers to high values of average output power while maintaining high efficiency. This method combines the gas-cooled-slab amplifier architecture with a pattern of amplifier pumping and extraction that is new to high-energy pulsed lasers, in which pumping is continuous and in which only a small…
Lawrence Livermore researchers have developed a novel waveguide with resonant leakage elements that frustrate guidance at well-defined and selectable wavelengths. Based on this waveguide, the LLNL team has fabricated a Large Mode Area Neodymium doped fiber with suppression of the four-level transition around 1060 nm, and demonstrated lasing on the three-level transition at 930 nm with good…
Lawrence Livermore researchers are the first to successfully develop a practical fiber-optic amplifier that generates significant optical gain from 1,390 nanometers (nm) to 1,460 nm with relatively good efficiency. This discovery enables the potential for installed optical fibers to operate in an untapped spectral region known as the E-band, in addition to the C- and L-bands where they…
LLNL’s system consists of one or more flashlamp-pumped Nd:glass zig-zag amplifiers, a very low threshold stimulated-Brillouin-scattering (SBS) phase conjugator system, and a free-running single frequency Nd:YLF master oscillator.
