Applied Energetics Strengthens IP Portfolio with Issuance of Two Breakthrough Patents in Raman Amplification and Coherent Optical Sources

TUCSON, AZ / ACCESS Newswire / September 10, 2025 / Applied Energetics, Inc. (OTCQB:AERG), a pioneer in ultrashort pulse laser (USPL) and advanced directed energy solutions, today announced the issuance of two critical patents from the U.S. Patent and Trademark Office that significantly advance the state-of-the-art 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.

"This invention enables a unique flexibility in wavelength selection and an increased efficiency in the generation of high-brightness, ultrashort laser pulses," said Dr. Stephen McCahon, Chief Science Officer of Applied Energetics. "By embedding the Raman amplifier directly into the pump cavity, we can finely tailor the pulse characteristics for specific applications, while extracting far more usable output energy from the same pump energy."

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.

"This is a fundamental leap in our ability to produce coherent light at exotic wavelengths using fiber-based Raman systems," said McCahon. "It opens the door to advanced sensing, spectroscopy, and long-wave infrared directed energy capabilities that were previously infeasible with legacy approaches."

Together, these patents expand Applied Energetics' growing portfolio of foundational technologies that underpin the company's Pulsed Lethality for Air Defense - Low Altitude (PLAID-L) platform, as well as future airborne, maritime, and space-based directed energy solutions.

Chris Donaghey, Chief Executive Officer of Applied Energetics, added, "These patents represent the kind of deep-physics innovation that sets Applied Energetics apart. As we rapidly mature our technologies for national security and commercial applications, our robust IP portfolio ensures we can protect, scale, and deploy these breakthroughs with confidence."

Applied Energetics continues to lead in the development of compact, agile, and high-impact directed energy systems that can defeat threats in sensor-saturated, fast-evolving battle environments with precision and minimal collateral effects.
