Abstract :
The experimental compact beam-former has demonstrated that an improved performance, over an original system, can be obtained with a much simpler and more compact optical arrangement. Output power has improved by 9dB through the use of fewer optical components and alignment adjustments. The spatial light modulator (SLM) phase control range has been maintained without any degradation caused by passing both laser beams through the SLM.
