Compact and energy efficient IR laser architecture (Conference Presentation)
Author(s): Dirk Hauschild; Stephan Schneider; Andre Gruetz

Paper Abstract

Multi-Stack IR diode laser sources in combination with micro-optics for beam forming allows the design and production of the most compact and efficient laser sources for high productive and selective heat treatment of surfaces and coatings in nearly all segments of industries. The direct diode approach without brightness destroying fiber delivery enables power densities above 10kW/cm² for high heating rates and accurate thermal envelopes with sub-second dwell times. Thanks to a special designed line beam profile the line length and related processed area per time can be scaled by putting several line segments together without any power or intensity drop at the stitching points of the line beam segments.
