Abstract
Here we report on the laser manufacturing of glass true 3D micro-optics. We demonstrate the feasibility of producing individual free-form geometry elements such as lenses, prisms, gratings proving the potential of integration into monolith stacked components. This is achieved by combining ultrafast laser 3D nanolithography and subsequent thermal post-treatment (calcination) - a novel approach introduced for additive manufacturing of inorganic materials [Nanoscale Horiz. 4, 647 (2019)]). The laser made pristine micro-optical components maintain their predefined shape while material is converted from hybrid polymer to glass corresponding to its inherent refractive index and transparency. This approach enables both realization of complex geometries and variation of material properties simultaneously.
