(a) The images of two-photon emission and fabrication in glass for a 2D 1 × 9 array and a 2D 5 × 5 SSTF multiple focal array. The images from left to right: two-photon image of 1 × 9 array, single-exposure fabrication on the glass surface of 1 × 9 array, two-photon image of 5 × 5 array, single exposure fabrication in glass with 30 μm depth of 5 × 5 array. Scale bar is 15 μm. (b) Left: Image of two-photon fluorescence arising from an SSTF array with designed intensity variation between each spot. Scale bar is 20 μm. Right: The line plots show an intensity profile along the central line of the left- and right-hand sets of 5 foci. The constant background offset was subtracted in the plots. (c) 3D multiple focal array of 11 spatiotemporal spots that were distributed at three different axial planes. The images of two-photon emission and fabrication in glass are presented. Scale bar is 15 μm. The SLM phases used to create these temporal arrays are presented in Supplementary Information Figure S3.
