摘要
A phase-modulator having only 'holes' (or 'bumps') on a quartz plate has been found to have insufficient depth-of-focus characteristics. This poor depth-of-focus can be attributed to phase retardation effect. Based on this, two bipolar phase-modulators were developed. The first has a deep depth-of-focus and the second is a single-plate modulator that can generate a two-dimensional light intensity profile. It was confirmed experimentally that the second modulator could grow arrays of large grains with 5-mu m pitch.
