Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiple output beam laser systems face inefficiencies and complexities in beam combining, particularly when using conventional methods that rely on symmetrical beams and partial reflectors, which limit power output, brightness, and flexibility, especially when scaling to high-power applications.
Innovation Solution
The development of optical and mechanical means to selectively rotate and reposition electromagnetic beams in one-dimensional or two-dimensional arrays within wavelength beam combining systems, allowing for flexible beam manipulation and coupling, which can be applied internally and externally in the laser cavity, enabling efficient beam combining along either the slow or fast axis dimension or a hybrid approach.

Engineering Contradiction Analysis
1Power
If conventional methods using symmetrical beams and partial reflectors are used to create multiple output beams, then the system structure is relatively simple, but the power output and brightness are limited
Solution Approach 1:
The patent segments the laser system into multiple independent laser emitters (first, second, third emitters) with different wavelengths, each contributing to a separate output beam. This segmentation allows parallel operation of multiple emitters to achieve high power output without requiring complex beam combining optics, as each emitter operates independently at its optimal wavelength and power level.
Solution Approach 2:
The patent introduces wavelength as an additional dimension for beam differentiation and combination. Instead of combining multiple beams of the same wavelength using complex spatial optics, the system uses wavelength-division multiplexing where each emitter operates at a distinct wavelength, allowing beams to be combined through wavelength-selective optics rather than spatial manipulation, thereby reducing combining complexity.

AI summary
A system and method for producing a multi-output laser by reconfiguring and apportioning a plurality of electromagnetic beams produced by various wavelength beam combining techniques. The reconfiguring of beams includes individual rotation and selective repositioning of one or more beams with respect to beam's original input position.
