The Lawrence Livermore National Laboratory is home to the world’s largest laser system, the National Ignition Facility (NIF). The NIF with its 192 beam lines and over 40,000 optics has been an engine of innovation for lasers and optics technologies for the last couple of decades. The Lasers and Optics intellectual property portfolio is the culmination of the many groundbreaking developments in high energy, high peak power and ultrashort pulse laser system design and operation, including technologies related to Laser Diodes, Fiber & Disk Lasers, Compact Telescopes, High Damage Threshold Gratings, High Power Optical Components and their Fabrication and Coating Techniques. The thrust of the research and development at the NIF has been to realize novel approaches for laser systems, optical components and their applications that are more compact and higher efficiency while reliably delivering ever higher energy and peak power capabilities required in the furtherance of LLNL’s missions in Stockpile Stewardship and High Energy Density Science.

Lawrence Livermore National Laboratory’s (LLNL) Space Program is now building an optical space domain awareness payload for an upcoming mission by the U.S. Space Force.
The planned mission, known as VICTUS HAZE, will be a tactically responsive space mission to demonstrate the ability to rapidly characterize an on-orbit threat.
The payload for VICTUS HAZE will use the LLNL monolithic telescope technology. LLNL’s monolithic telescopes are built out of a single piece of fused silica, eliminating the need for alignment and calibration after manufacture, while still providing the best possible resolution.
LLNL’s monolithic telescope was developed and patented by Lab employees Willem de Vries and Brian Bauman and former Lab employee Alex Pertica.
R&D World Magazine recently announced their 2022 award winners. LLNL researchers received three awards, which include Tailored Glass by Direct Ink Writing, novel compression gratings that enable a new class of high-energy laser systems and a 3D printing feedstock known as Energy Inks that can print a functioning battery.
NASA's funding will enable LLNL and Kentucky-based space life sciences company, Space Tango to mature prototypes of the “replicator” technology — a ultrafast 3D printer co-developed by LLNL and the University of California, Berkeley — for bioprinting in microgravity on the International Space Station.
Rapid monolith development at scale is achieved through use of a functionally equivalent optic simulant made from a low-cost material to substitute the functional optic. Monolith optical performance is affected not only by thermal expansion but also by temperature inhomogeneity due to the temperature dependence of refractive index.
Aeroptics are a proposed new class of monolithic optical system in aerogel fabricated by molding around a master mandrel. This approach combines the intrinsic stability of proven monolithic telescopes, with the ultralow density of silica aerogels. In Aeroptics, the monolith is hollow with an aerogel substrate providing a supporting structure. Theoretically, Aeroptics could enable 1-m aperture…
This invention achieves both a wider field of view and faster f-number within a monolithic substrate by incorporating an aspheric convex refractive first surface and a planar aspheric field corrector surface on the final refractive surface. These two refractive surfaces work in conjunction with a concave aspheric primary and convex aspheric secondary mirror (e.g. Cassegrain type) to improve…
Monolithic Telescopes are a novel implementation of a solid catadioptric design form, instantiated in a monolithic block of fused silica.
The LLNL method for optimizing as built optical designs uses insights from perturbed optical system theory and reformulates perturbation of optical performance in terms of double Zernikes, which can be calculated analytically rather than by tracing thousands of rays. A new theory of compensation is enabled by the use of double Zernikes which allows the performance degradation of a perturbed…
LLNL is developing the Space-based Telescopes for Actionable Refinement of Ephemeris (STARE). STARE is a constellation of low cost nano-satellites (less than 5Kg) in low-earth orbit dedicated to the observation of space debris in conjunction with a ground-based infrastructure for maintenance, coordination and data processing. Each nano-satellite in the constellation is capable of recording an…
