Explanation for the Mode Instability in High-power Fiber Amplifiers with Few-mode Fibers
Updated: 2011-05-28 14:16:00
Two recent scientific papers discuss the suspected physical origin of a very nasty mode instability, as has been observed in some very high-power fiber amplifiers. The latest paper by A. V. Smith can be considered as reporting breakthrough results, very much clarifying the situation.
