Industrial stacked laser brightness increasing system having laser assembly output beams spatial slot filter focussed and collimator output beam coupling mirror passing.

摘要

The laser brightness increasing system has an assembly of lasers (LSC1 to LSC4) transmitting in parallel directions. The output beams are focussed (L1) onto a spatial filter (FS) at a focal point (F). The spatial filter is a slot or diaphragm. the output beam is collimated (L2) and passed to a coupling mirror (MC).
