Novel Laser Power Sensor Improves Process Control

Lasers are used to process materials in a wide variety of applications in industries such as semiconductor electronics, medical product manufacturing, consumer product packaging and automotive production. While these uses involve many different laser technologies working with many different materials, they often require the same regular measurements of laser output characteristics such as power, pulse energy, pulse shape or beam profile to ensure optimum and consistent processing.  This white paper reviews a new laser power measurement technology specifically designed for use in laser-based processing tools, which directly addresses these needs.
