Abstract
High power fiber lasers include large or very large mode area active fibers. Mode preserving pump combiners are situated to counter-pump the active fiber using one or more pump sources. The mode preserving pump combiners preserve single mode propagation in a signal fiber, and such combiners can be identified based on optical spectra, beam quality, or temporal response. Active fibers can also be included in a pump combiner so that the active fiber is splice free from an input end that receives a seed pulse to an output end. Peak powers of over 100 kW can be obtained.
