Precision Diode Laser Processing Innovative Products and Systems for Diode Laser Control and Regulation Amtron GmbH, based in Aachen, Germany, develops and markets highquality laser-diode controllers and laser-diode systems for industry. Amtron was founded in 2000 as a spin-off from the Fraunhofer Institute for Laser Technology (ILT-FHG) and is positioned as a specialist in the development of innovative, high-quality products and solutions. Clients include laser manufacturers, system integrators and research & development specialists using Amtron systems for the monitoring and control of diode lasers in machining or medical technology. Laser Diode Controller Series CS400 Power supplies with process control CS400 series devices supply constant current at up to 300 A and pulsed current at up to 2000 A with a pulse width as of 10 µs. With innovative functions such as broken fiber detection and power regulation, these devices monitor and protect the complete processing procedure of CW and pulse lasers.

The device offers a range of connections via different fieldbus systems. The process controller uses various input parameters such as feedrate, external sensors or trigger/gate to calculate and control the analog and digital laser power. The control unit modulates the amplitude, pulse width, or frequencies with fast cycle times of 1µs. In contrast to conventional system controllers, the CU190 process controller offers fully customizable laser control, which easily integrates into existing processes.
