Abstract

Rapid multi-focus multi-photon laser printing suffers from insufficient photoresist sensitivity and limited focus quality. To overcome these problems and enable even higher printing rates, we present a novel approach for low-aberration and large field-of-view multi-focus printing with 7×7=49 foci at high focus scanning speeds. This is achieved by a combination of two 3D laser nanoprinted micro-optical elements: A low diffraction-order diffractive beam splitter to circumvent chromatic aberrations and an aspheric-lens array. The latter separates the diffracted beams to get a sufficient focus spacing. Together with highly sensitive photoresists we then allow for nanostructured sample dimensions inaccessible before.
