Applied Energetics issued two U.S. patents in Raman amplification

Applied Energetics (AERG) announced the issuance of two critical patents from the U.S. Patent and Trademark Office that significantly advance the in laser-driven optical amplification and tunable, multi-wavelength light sources. U.S. Patent No. 12,362,531 titled “Resonating Optical Amplifier with Shared Raman Gain Cavity” introduces a novel architecture that co-locates a Raman amplifier within a laser pump cavity-maximizing energy transfer, brightness, and amplification efficiency by capturing and reusing residual pump energy that is typically wasted in conventional systems. U.S. Patent No. 12,413,039 titled “Multiple Coherent Wavelength Optical Sources via Raman Amplification” describes a tunable system that uses a supercontinuum master oscillator to seed Raman amplifiers driven by quantum cascade laser pumps-producing multiple selectable, high-brightness coherent wavelengths from a compact, scalable architecture.
