Journal ArticleDOI

Efficient High-Power Laser Diodes

Paul Crump, +11 more
- 06 Feb 2013 - 
TL;DR: In this paper, a review of efforts to increase ηE is presented and it is shown that for well-optimized structures, the residual losses are dominated by the p-side waveguide and nonideal internal quantum efficiency.
Journal ArticleDOI

Comparative theoretical and experimental studies of two designs of high-power diode lasers

K.-H. Hasler, +7 more
- 01 Apr 2014 - 
TL;DR: In this article, an extreme double asymmetric design to mitigate the impact of the p-side waveguide is studied and compared with a more conventional design, and an increase of the efficiency at the highest power is demonstrated, but it is less than expected from simulations.
Journal ArticleDOI

High Beam Quality in Broad Area Lasers via Suppression of Lateral Carrier Accumulation

Martin Winterfeldt, +5 more
- 01 Sep 2015 - 
TL;DR: In this article, the authors show that carrier accumulation at the edges of the contacts can be eliminated and that as a consequence, near and far field are narrowed and the rate of increase of beam parameter product (BPP) with self-heating reduces by 35%.
Proceedings ArticleDOI

975-nm high-power broad area diode lasers optimized for narrow spectral linewidth applications

Paul Crump, +8 more
- 11 Feb 2010 - 
TL;DR: In this paper, three different diode laser device designs have been developed and discussed and are discussed and compared using a Volume Bragg Grating (VBG) for VBG use.
Proceedings ArticleDOI

Low-loss smile-insensitive external frequency-stabilization of high power diode lasers enabled by vertical designs with extremely low divergence angle and high efficiency

Paul Crump, +12 more
- 26 Feb 2013 - 
TL;DR: In this paper, the authors showed that VHG-stabilized ELOD-based diode lasers have significantly lower loss and larger operation windows than conventional diode laser designs in the collimated feedback regimes, even in the presence of significant (≥ 1 μm) bar smile.
