Abstract
A system comprising a beam source (110) and an optical system (304) comprising first and second portions. The system further comprises first and second torque motors integrated into respective ones of the first and second portions, The first torque motor (420) is configured to rotate first portion (416) around a first axis (434). The second torque motor (426) is configured to rotate second portion (418) around a second axis (436). The first axis is perpendicular to the second axis.
Claims23
A system comprising:
- a light source that produces a pulsed laser beam with pulse bursts comprising two sub-pulses per pulse burst or more;
- an optical system comprising first and second portions;
- and
- first and second torque motors integrated with respective ones of the first and second portions,
- wherein the first torque motor is configured to rotate the first portion around a first axis;

A method comprising:
- generating, by a system, a quasi-non-diffracting beam;
- directing the quasi-non-diffracting beam onto a transparent workpiece, generating an induced absorption and producing a defect within the transparent workpiece;
- and
- moving, by the system, the quasi-non-diffracting beam relative to the transparent workpiece along a contour line, forming a contour with a plurality of defects in the transparent workpiece,
- wherein the quasi-non-diffracting beam is oriented orthogonal to an impingement surface of the transparent workpiece at an impingement location, and
- wherein an orthogonal orientation between the quasi-non-diffracting beam and the impingement surface is maintained as the quasi-non-diffracting beam moves along the contour line to different locations on the curved surface of the transparent workpiece that have different surface orientations.
