Stackable laser beam module assembly

Abstract

A stackable beam module assembly and system for combining laser beams by recursive coupling of one or more beam modules, wherein a central beam propagates through a central channel of each module and peripheral beams introduced through peripheral channels are directed in a direction parallel to the central beam, to thereby propagate a resultant beam having an increased power output directly correlated to the sum of the combined laser beams.

AI Technical Summary

Benefits of technology

The present invention provides a beam module assembly that can be easily linked together to form a single beam. The use of standard and commercially available components allows for the use of less expensive and lower performance components, improving the economics and accessibility of the assembly. The beam module assembly includes a housing with a central beam channel and input and output ports, a converging lens and a diverging lens to refract and propagate beams in a specific way. The assembly also includes a peripheral beam channel with a peripheral input port and a secondary converging lens and a secondary diverging lens to produce a smaller beam. The technical effects of the invention include improved adaptive versatility, reliability, and scalability for manufacturing and distribution.

Problems solved by technology

The efficacy of laser devices for such multifarious applications have led to the design and manufacture of many diverse laser instruments and equipment limited to specialized, dedicated and customized use.

In contrast, the high cost and lack of adaptive and diverse applications to common uses of conventional laser devices as well as the scarcity, and perhaps unavailability, and expense of components, especially for sophisticated and high-power applications, and repair services continue to limit their accessibility and use.

In conventional laser beam systems with one or few laser sources, the failure of a single source can result in significant loss of performance.

The cost of high-power laser systems is increased due to the limited number of laser sources that can be combined, wherein each source must be proportionately powerful to produce the desired overall beam power.

As the power level of each individual laser source is increased, the scarcity and cost also increase in an exponential relation, for example a laser with twice the power might have ten times the cost and require highly specialized components.

However, such existing methods for combining beams have limited capacity and application.

That is, conventional assemblies are limited to a fixed number of laser sources / elements having limited and specialized applications and lacking adaptive functionalities for adjusting power levels in accordance with a particular application in order to boost efficiency.

Further limitations of prior art laser devices include restrictions for particular frequencies and from combining multiple beams having the same frequency.

Such and other limitations on the versatility and adaptability of conventional laser systems have led to multiple disadvantages and drawbacks that have narrowed their use to limited and specialized applications and markets.
