Abstract The liquid crystal (LC) panel of a commercially-available LCD projector is successfully used for beam shaping, and a Gaussian beam is converted to a square super-Gaussian beam using the configuration of amplitude modulation. The additional phase modulations imposed by the LC modulator on the shaped beams are measured precisely using an interferometric technique. The experimental results have demonstrated that such a commercially-available programmable spatial light modulator is applicable to beam shaping with negligible additional phase modulation.
