Novel In-Plane Semiconductor Lasers XVIII.
More and more applications are using GaN laser diodes. Visible blue laser devices are well established light sources for converter based business projection of several thousand Lumens. Additional laser-based concepts like near-to-eye projection push

We present the improvements in power conversion efficiency of high power multi-mode blue laser diodes. The improved device architecture shows a peak wall plug efficiency of ∼ 44.2 % at room temperature. Furthermore, the device delivers an optical o

The range of applications of blue and green lasers is increasing from year to year. Driving factors are costs and performance. On one hand we study the characteristics of low power R&D c-plane laser structures with improved Gaussian vertical and hori

Blue and green InGaN-based R&D laser structures on c-plane GaN substrates are investigated. We analyzed carrier injection efficiencies as well as internal quantum efficiencies up to laser threshold. The injection efficiency of the blue laser structur
