1. A laser system comprising:
- A plurality of electromagnetic radiation sources each configured to produce a unique wavelength emission beam;
a first and second optical element configured to collectively reduce the image size of the array of emission beams along a first dimension;
a third optical element configured to receive the reduced-in-image size emission beams and overlap the beams along the first dimension;
a dispersive element positioned at a region of overlap to receive and transmit the overlapped beams as a multi-wavelength beam; and
a partially-reflective output coupler arranged to receive the multi-wavelength beam, to reflect a portion of the multi-wavelength beam back to the dispersive element, and to transmit the multi-wavelength beam,wherein the first and third optical elements collectively are configured to image the array of emission beams along a second dimension.

Abstract
A Compact Interdependent Optical Laser System and Method is designed for use with wavelength beam combining (WBC) systems that utilize both slow-axis and fast-axis WBC. Multiple optical elements having individual and interdependent functionality allow for the system to compact reducing the overall footprint of the system. Additional, configurations incorporating the compact system described herein allow for high-power and brightness scaling.
