Fast-axis collimator array

摘要

A micro-optical element for use with an edge-emitting laser diode bar stack, the element comprising a plurality of spaced apart fast-axis collimators formed as a monolithic array, wherein the spacing between the collimators in the fast-axis varies across the micro-optic element. A method of manufacturing a micro-optical element for use with a laser diode bar stack, using a wavelength stabilized CO2 laser is also described.
