Near 1 kW of continuous-wave output power has been obtained from a single 1-cm-wide diode-laser bar. Mounted on a water-cooled microchannel heat sink, the operating wavelength was near 940 nm (at ~400 W) and the measured thermal resistance was as low

In this work we show that mini-bar-based 8xx products show the reliability characteristics of independent emitter failures and "non-degrading" drift plots similar to those of their 9xx counterparts. This fact is in part an outcome of the bonding proc

New-generation multi-mode 9xx mini-bars used in fiber pump modules have been developed. The epitaxial designs have been improved for lower fast-axis and slow-axis divergence, higher slope efficiency and PCE by optimizing layer structures as well as m

As GaAs based laser diode reliability improves, the optimum architecture for diode pumped configurations is continually re-examined. For such assessments, e.g. bars vs. single emitters, it is important to have a metric for module reliability which en
