Abstract: An apparatus that enables real time measurement of the spatial profile, circularity, centroid, astigmatism and M2 values of a laser beam generated by a high power laser beam. The apparatus employs the optics used in a process application, including a focus lens and cover glass. An attenuation module includes a pair of high reflecting mirror plates disposed in parallel, spaced apart relation to one another at a common angle of incidence to the laser beam. A beam dump is positioned out of a path of travel of the laser beam and in receiving relation to light reflected by the first and second mirrors. A camera detects spots of light that pass through the first and second mirrors. A high power attenuator formed by a highly reflective mirror pair is positioned between the source and the attenuation module. A second embodiment includes a single mirror plate having highly reflective surfaces.

Abstract: A focused laser beam having an optical axis passes sequentially through a simple, positive lens, a pair of plane, parallel windows, and a second, simple, negative lens. Each of the plane, parallel windows are mounted to a galvanometer motor and positioned orthogonally to one another. The focused laser beam is therefore displaced in a controlled manner from the optical axis to enable laser machining of very precise geometric features over a large processing window. A field size of one thousand microns is achieved.

Abstract: An apparatus having a linear structure that enables real time measurement of the spatial profile, circularity, centroid, astigmatism and M2 values of a laser beam generated by a low power laser beam. A laser beam source transmits a laser beam through a focusing lens, a Fabry-Perot resonator, a pair of polarizers and a camera that detects spots of light that pass through the first and second mirrors and the polarizers. The resonator includes a pair of high reflecting mirror plates disposed in parallel, spaced apart relation to one another at a common angle of incidence to the laser beam. The polarizers are disposed at an opposite angle of incidence and are rotationally adjustable to enable intensity adjustment of the camera.

Abstract: A method for thermally compensating lenses in an optical system for high power lasers includes the steps of providing a fused silica lens to collimate a high power laser beam and positioning that lens in collimating relation to the laser beam. A focusing lens assembly is provided to focus the collimated laser beam and is positioned in focusing relation to the collimated laser beam. At least one lens having a negative dn/dT to offset a heat-induced change in index of refraction of the fused silica lens is included as a part of the collimating lens assembly and as a part of the focusing lens assembly. The lens having a negative dn/dT is selected from a group of glasses having a negative dn/dT. The power of the lenses is balanced with an offsetting negative dn/dT so that the optical system maintains its focus over a wide temperature range.

Abstract: A focused laser beam having an optical axis passes through a first lens mounted to a first galvanometer and a second lens mounted to a second galvanometer. The first galvanometer is adapted to tilt the first lens about a X axis and the second galvanometer is adapted to tilt the second lens about a Y axis. This displaces the focused laser beam in a controlled manner from the optical axis to enable laser machining of very precise geometric features over a large processing window. In a preferred embodiment, the first and second lenses are a pair of inverted positive meniscus lenses, of high index of refraction material.
