Resilient Ultra Short Pulsed Laser Sources - RFI

The Defense Advanced Research Projects Agency Multi X Office issued Request for Information DARPA-SN-26-124 to identify industry, academic, and government capabilities regarding resilient, compact, and rugged millijoule-class ultra-short pulsed laser sources. The primary objective is to gather information on fieldable architectures that can maintain mode-locking and operational stability while subjected to environmental challenges, such as thermal stress, vibration, and acceleration, specifically referencing MIL-STD-810H standards for operational aircraft. DARPA is seeking data on pulse width, energy, average power, and repetition rate tuning, as well as strategies for waveform generation and environmental robustness. This RFI is intended solely for program planning and information purposes and does not constitute a formal solicitation or a binding contract. Interested parties must submit concise responses by November 20, 2026, at 5:00 p.m. ET. Submissions must follow strict formatting guidelines, including 12-point font and 1-inch margins, and must be organized into a cover page, technical discussion, and a references page. Unclassified responses should be sent to [email hidden], while classified responses require prior coordination with the agency. All proprietary information must be specifically marked within the submission.
