Abstract
A beam integrator system, which integrates multiple beams into fewer beams of increased intensity by using a combination of optical elements and lenses.
Claims16
A beam integrator comprising:
- a laser diode array, where the diode array contains a plurality of emitters:
- and
- an optical array, where the optical array is composed of optical array elements, each optical array element associated with an emitter, where each emitter emits an associated beam making a plurality of beams, where the optical array integrates the plurality of beams into fewer beams of increased relative intensity.
A beam integrator system comprising:
- a laser diode located near the first end of a housing structure;
- a plurality of emitters which are positioned in an end-to-end position with respect to one another and located within the laser diode;
- a plurality of microlens, wherein each microlens is attached and aligned with one of the plurality of emitters;
- a plurality of dove prisms which are positioned in an array and wherein each of the dove prisms are respectively aligned with each corresponding emitter and a microlens;
- and
- an integrator lens.

A method of integrating a plurality of beams to form a beam with a near circular cross-section, comprising:
- rotating beams by an angle to obtain associated rotated beams, wherein the beams are generated by a plurality of emitters, and where the rotating step is performed by an array of optical elements;
- combining the associated rotated beams by passing the associated rotated beams through a positive lens to form at least one combined beam;
- and
- varying the cross section of the combined beam, by passing the at least one combined beam through an anamorphic lens.

An optical device emitting coherent energy in a single collimated beam comprising:
- an array of laser emitters arranged with a regular and predetermined pattern and spacing;
- a microlens array having:
- a plurality of incident micro-lens each corresponding to a said laser emitter and collectively having a pattern and spacing complementary to the predetermined pattern and spacing of the laser emitters for focusing the energy emitter from said laser emitters;
- and
- additional microelements collimating the energy emitted by said laser emitters and focused by said incident micro-lens to produce a collimated and phase coherent combination of the outputs of each of said laser emitters to decrease the size of and increase the concentration of the emitted coherent energy.
