Laser Auto-Focus Technology for High-Precision Material Processing This article introduces multiple laser auto-focus (AF) methods—including optical, image, and laser-induced techniques—alongside deformable mirror applications for precise focal control.
Optical-based AF delivers high accuracy and fast response, image-based AF handles complex surfaces flexibly, and laser-induced AF offers excellent interference resistance.
Adaptive optics using deformable mirrors enables rapid (up to 2 kHz) and accurate focus shifts, paving the way for intelligent, high-speed laser processing systems.
