Abstract

The invention provides a laser (10) focusing system in which a phase pattern of a laser fabrication signal is controlled using a spatial light modulator (16) to provide correction for optical aberration resulting from a refractive index boundary at a lateral edge of the sample. The lateral edge has distance to the laser focus which varies as the structure is fabricated, giving different degrees of overlap of the laser fabrication beam over the edge of the sample. This aberration correction enables focusing of a laser output right up to the edge of a sample.
