Abstract
We report on the coherent combination of two chirped pulsed fiber lasers. The beams coming from two core diameter ytterbium-doped rod-type fibers were coupled in a Mach-Zehnder-type interferometer by means of a polarization beam splitter. Active stabilization of the interferometer was achieved by using a piezo-mounted mirror driven by a Hänsch-Couillaud polarization detection system. Pulses with energy and a compressed duration of were obtained. This, compared with the coming from each single amplifier, results in a combining efficiency as high as 91%.
