Abstract
A beam combining system suitable of pulsed fiber laser applications is able to produce non-spatial-dispersive beams using an highly efficient filter, such as a multilayer dielectric filter, in transmission and reflection configurations. The techniques therefore can overcome constraints on laser line-width and beam width and allow for more stable systems for high peak power pulsed laser energy, such as may be used in extreme ultraviolet lithography and other applications.
