Patent ID: 7161113

Claim:
A laser machining system comprising: a work-piece; at least one light source that produces a laser light along a first axis, the laser light defining a first portion of laser light and a second portion of laser light, the first portion includes collimated light, the second portion includes noncollimated light, the second portion being radially inward relative to the first portion; an optical element that reflects the first portion of laser light at an angle relative to the first axis so that the second portion of laser light passes through the optical element along the first axis; a first optical assembly that collimates the first portion of laser light into a first light beam of a first cross-sectional area onto the work-piece at a sufficient power density to machine the work-piece; and a second optical assembly that collimates the second portion of laser light into a second light beam having a second cross-sectional area onto the work-piece at a sufficient power density to machine the work-piece, the second optical assembly including a redirecting assembly and a telescopic arrangement to redirect and collimate the second portion of the laser light into the second light beam toward the work-piece so that the second light beam is spaced apart relative to the first light beam.
