Presented at ICALEO 2007

The field of laser applications is so broad that a multitude of laser architectures is needed to satisfy it. This multitude of architectures, however, may be powered by comparatively few optical "engines" designed specifically to allow the laser designer the greatest freedom and flexibility in tailoring his design to reliably meet each application's unique set of specifications. We present here a family of such diode pumped laser amplifier modules and their principal charact...

ICALEO 2007 Paper #502 (High Power Diode Lasers for Industrial Applications)

High Power Diode Lasers for Industrial Applications
Authors:
Wolfgang Horn, DILAS Diodenlaser GmbH; Mainz Germany
Presented at ICALEO 2007

New wavelengths, high brightness and increasing reliability are breaking new ground for diode lasers. The higher brightness allows direct fibre coupling of several 100 W in 200 μm and 400 μm fibres and therefore the pumping of fibre lasers. Such high power fibre coupled laser diodes combined with fast beam deflection units (Galvo Scanners) have been implemented in industrial processes and used for quasi-simultaneous welding of polymers, heat treatment in the sub millimetre range or selective soldering in solar cell production. Available as modules or as tu...

Diode Pump Requirements for High Power Fiber Lasers
Authors:

Presented at ICALEO 2007

The single most important factor in the recent power scaling of CW fiber lasers has been the continuing improvement in fiber coupled, high brightness pump diodes. As the available power/brightness per module has increased the cost associated with pumping a fiber laser has decreased and in turn the available CW power from a single fiber laser has increased from 100W to over a kWatt. In this talk we review some of the unique requirements associated with pumping high power fiber lasers in various architectures, the roa...

Presented at ICALEO 2007

Direct Laser Deposition (DLD) is an emerging technology which shows great potential for direct manufacture. The DLD method has become viable for the build up of three-dimensional parts, their repair or modification, as a means of rapid prototyping and tooling of metallic components. However, compositional monitoring of the DLD process is still requires investigat...
