Registered-Channel Multiplexer

Registered-Channel Multiplexer Overview

AOT's free-space registered-channel multiplexers (RCM) produce laser beams with temporally modulated characteristics including power, color, spatial mode, divergence, or polarization, with low insertion loss and inter-channel pointing stability better than one arc-second.  These multiplexers provide novel capabilities for high-speed remote-sensing, microscopy, and material-processing with low- or high-power lasers, and can be integrated with active imaging systems, lasercom systems, lidars, and laser-machining systems.
