Fast Modal Analysis and Transverse Mode Instability (TMI) Mitigation in High Fiber Amplifiers

Technology #11647

Key Points

  • Two innovations for improving fiber laser performance and output power
  • One innovation is a technique for fast modal analysis of fiber lasers
  • The second innovation is a spatial mode profile modulation method for mitigating transverse mode instabilities (TMIs)

Abstract

The University of Central Florida invention describes performance improvement methods for high-power laser systems. The techniques include:

  • Fast modal decomposition, which allows the quantification of optical modes present in optical beams at high speeds and in real-time without optical references
  • Time-dependent excitation of selected modes to suppress transverse mode instability (TMI) without relying on feedback
