Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A method comprising the steps of: providing a flexible composite material the composite material being a layered composite material and each layer of the composite material having respective optical, mechanical, and thermal properties; aligning a laser source with a portion of the composite material to be processed; operating the laser source to generate laser beam pulses; and forming separate composite material elements by applying the pulses of beams from the source to the composite material portion to be processed.
Claim 2
Independent Claim
79 words
A method comprising the steps of: providing a flexible composite material the composite material being a layered composite material and each layer of the composite material having respective optical, mechanical, and thermal properties; aligning a laser source with a portion of the composite material to be processed; operating the laser source to generate laser beam pulses; and forming separate composite material elements by applying the pulses of beams from the source to the composite material portion to be processed.
Claim 3
Dependent Claim
49 words
A method in accordance with claim 1 wherein aligning the laser source comprises the steps of: operating the laser source so that a low power alignment beam is generated; and adjusting the orientation of the low power alignment beam relative to the portion of the object to be processed.
Claim 4
Dependent Claim
45 words
A method in accordance with claim 2 wherein adjusting the orientation of the low power alignment beam comprises the step of: adjusting the orientation of a focusing lens relative to the composite object, the focusing lens being disposed in the laser source beam optical path.
Claim 5
Dependent Claim
71 words
A method in accordance with claim 1 wherein the laser source includes a laser head, an optical fiber and an output coupler, the optical fiber being disposed to transmit laser beam pulses emitted from the laser head to the output coupler, and aligning the laser beam emitted from the output coupler comprises the step of: adjusting the orientation of the output coupler relative to the composite object portion to be processed.
Claim 6
Dependent Claim
14 words
A composite object element formed in accordance with the method recited in claim 1.
Claim 7
Independent Claim
153 words
An apparatus for creating at least two separate composite objects from at least one homogeneous composite object, said apparatus comprising: a flexible composite material means being homogeneous layered composite material and each layer of the composite material having respective optical, mechanical, and thermal properties; means for aligning a low power beam emitted from a laser source with a portion of the homogeneous composite material to be processed, said aligning means comprising means for operating the laser source so that a low power alignment beam is generated and means for adjusting the orientation of the low power alignment beam relative to the portion of the material to be processed; means for generating laser beam pulses, the laser beam pulses being substantially coaxial with said previously generated low power alignment beam; and means for forming separate composite material elements including means for applying the pulses of beam to the composite material portion to be processed.
Claim 8
Independent Claim
153 words
