Abstract:

A method for adjusting the wavelength and dominant mode of a laser fiber prior to installation in a laser assembly includes the steps of linearly stretching the laser fiber so as to modify its output wavelength, axially twisting the laser fiber so as to modify its dominant mode, and affixing the laser fiber to a laser assembly in its linearly stretched and axially twisted condition. The laser assembly includes a dynamic tuning mechanism for wavelength adjustment during use. The twisted and stretched fiber has an unadjusted wavelength and dominant mode that are within a selected range before adjustment by the dynamic tuning mechanism.
