Theory of Transverse Mode Instability in Fiber Amplifiers with Multimode Excitations
Kabish Wisal, Chun-Wei Chen, Hui Cao +1
Transverse Mode Instability (TMI) which results from dynamic nonlinear thermo-optical scattering is the primary limitation to power scaling in high-power fiber lasers and amplifier…
Generating and processing optical waveforms using spectral singularities
Asaf Farhi, Alexander Cerjan, A. Douglas Stone
We show that a laser at threshold can be utilized to generate the class of coherent and transform-limited waveforms at optical freque…
Mitigating stimulated Brillouin scattering in multimode fibers with focused output via wavefront shaping
Chun-Wei Chen, Linh V. Nguyen, Kabish Wisal +9
The key challenge for high-power delivery through optical fibers is overcoming nonlinear optical effects. To keep a smooth output beam, most techniques for mitigating optical nonli…
Theory of Stimulated Brillouin Scattering in Fibers for Highly Multimode Excitations
Kabish Wisal, Stephen C. Warren-Smith, Chun-Wei Chen +2
Stimulated Brillouin scattering (SBS) is an important nonlinear optical effect which can both enable and impede optical processes in guided wave systems. Highly multi-mode excitati…
