Paper Abstract

An overview is presented on the recent progress in the development of high power laser bars at wavelengths around 1060nm. The development is focused on highly efficient and reliable laser performance under pulsed operation for medical applications.

The epitaxial structure and lateral layout of the laser bars were tailored to meet the application requirements. Reliable operation peak powers of 350W and 500W are demonstrated from laser bars with fill-factor FF=75% and resonator lengths 1.5mm and 2.0mm, respectively. Moreover, 60W at current 65A with lifetime <10.000h are presented. The power scaling with fill-factor enables a cost reduction ($/W) up to 35%.
