The Department of Energy, through the Lawrence Livermore National Laboratory (LLNL), is offering a collaboration opportunity to further develop and commercialize its High Power Microstructured Optical Fiber Amplifier Design aimed at mitigating stability limitations. This innovative technology addresses the challenges of scaling high power fiber amplifiers beyond a few kilowatts by proposing a new microstructured fiber design that enhances core mode confinement and suppresses undesirable Transverse Mode Instabilities. The potential applications for this technology include high power fiber lasers and amplifiers for materials processing, with the current development status at Technology Readiness Level (TRL) 4-5. Interested companies are encouraged to submit a statement of interest, including relevant corporate expertise and contact information, to LLNL's Innovation and Partnerships Office by email or written correspondence, with further details available on their website.
