摘要

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 process and heat-sink design. Multi-cell life testing gives projected reliable operation of compact, fiber-coupled modules (200-mu m-diameter, 0.15 NA) at 30 W and 808 nm, with 35 W at 880 nm.
