High Brightness Direct Diode Lasers

DirectProcess 900

Direct Diode Laserengine for Material Processing

Wavelength: 900 nm to 990 nm
Power: Up to 1000 W

A fiber coupled direct diode laser system with integrated driver 
electronics and microprocessors with standard industrial interfaces. It features an ultra-high brightness beam performance and detachable industrial standard delivery fibers. An integrated micro-processor allows a fast modulation capability with pre-programmable pulse forms. The data logging capability and real time system health status monitoring enables a predictable life cycle management. The Light Engine is controlled via standard industrial interfaces as: USB, Analog I/O, Ethernet (TCP/IP), ProfiBus which allows local and remote operation and diagnostic. The System is monitored by Power Monitor, Back Reflection Sensor, Humidity Sensor, Temperature Sensor, Water Flow Sensor and Fiber Interlock (with QBH or LLK-HP).
