Abstract

Within the German national research project "Briolas" Osram Semiconductors and Laserline GmbH cooperated in the subproject "Brilasi" which focused mainly on Brilliant Laser Diodes for Industrial Applications. The project was finished in December 2007 and lasted more than three years. Laserline and Osram are investigating the performance of broad area diode lasers with a bar width from 1.0 to 10.0 mm in high brilliance diode laser beam sources. Within the program different fibre coupled laser sources are built up: 1. Fibre coupled diode laser beam source with a Beam Parameter Product (BBP) of 40 mmxmrad built from diode laser bars with 10 mm bar width. 2. Fibre coupled diode laser beam source with a BBP of 20 mmxmrad built from Mini-Bars with a bar width of 3.0 mm and 8 emitters. These Different solutions are characterized regarding the electro optical performance. The laser output characteristics are determined for the diode laser device as well as the complete beam source. Lifetime tests are conducted to determine the long term stability of the prototypes and the different chip material.
