Query: Nanoscale precision of 3D polymerisation via polarisation control   A systematic analysis of polarization effects in a direct write femtosecond
laser 3D lithography is presented. It is newly shown that coupling between
linear polarization of the writing light electric field and temperature
gradient can be used to fine-tune feature sizes in structuring of photoresists
at a nanoscale. The vectorial Debye focusing is used to simulate polarization
effects and a controlled variation up to 20% in the linewidth is shown
experimentally for the identical axial extent of the polymerised features. The
revealed mechanisms are relevant for a wide range of phenomena of light-matter
interaction at tight focusing in laser-tweezers and in plasmonic or dielectric
sub-wavelength focusing where strong light intensity and thermal gradients
coexist.
