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.

NASA funds LLNL to demonstrate 'replicator' 3D printer to produce cartilage in space

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.

HAPLS

LLNL researchers have developed a high average power Faraday rotator that is gas-cooled and uniquely designed to dissipate heat uniformly so that it does not build up in the optical component and affect its performance.  The Faraday rotator material is sliced into smaller disks like a loaf of bread so that high speed helium gas can flow between the slices.  With this highly efficient cooling…

The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS), the world’s most advanced and highest average power diode-pumped petawatt laser system, at LLNL.

This invention discloses a method to minimize transient variations in the wavelength- and/or pointing-behavior of an optic, without requiring a reduction in its thermal resistance, optical absorption, or operating irradiance. The invention employs a combination of a time-varying heat source and time-varying thermal resistance and/or heat sink temperature to achieve temperature stability of the…

NIF Target Chamber

This invention concerns a new type of optic: a transient gas or plasma volume grating produced indirectly by small secondary lasers or directly by nonlinear processes using the primary beams themselves. When used in conjunction with advantageously placed shielding it offers a means of protecting the final optical components of a high-repetition-rate IFE facility. These transmission optics are…
