Diode laser beam combiner system

摘要

A small, scalable, and inexpensive semiconductor diode laser system is described that includes a diode laser beam combiner comprising a cylindrical microlens, a lens array, and a fan window that optically combines energy outputs of at least two diode laser emitters or emitter groups. The diode laser beam combiner first collimates the diode laser energy and then optically combines the energy along a pre-determined axis, thus limiting effects due to space between the diode laser emitters. A chosen spot size and shape can be achieved by manipulating the number and size of lens array and fan window steps. Maximum power density and beam brightness available from the diode laser emitters or emitter groups is thus available at a work or treatment site.
