These arrays feature a new epitaxial wafer design that utilises a large optical cavity and are packaged using AuSn solder and CTE-matched heat sinks. This work focuses on life test matrix of multiple epitaxial structures, multiple wavelengths and multiple drive currents.
Particular emphasis is given to the 80x and 88x wavelength bands running at 100-300 Watts per bar. Reliable operating
points are identified for various applications including range finding (product lifetimes less than 1 billion shots) and
industrial machining (product lifetimes greater than 20 billion shots).
In addition to life test data, a summary of performance data for each epitaxial structure and each bar design is also presented.
