Investigates efficiency changes with pulse energy, laser spot size, and cooling temperature using coupled field-phase-heat equations with thermal effects and phase mismatch analysis.

Abstract: This work investigates instabilities that can occur during pulse propagation along optical fibers. They can have physical origin, as the modulation instability, or being just numerical ...
