      abstract     = {This study explores how laser light affects the morphology
                      of tetracene films, and it presents novel strategies for
                      improving the creation of thin films used in
                      (opto-)electronic devices. We demonstrate that laser light
                      (532 nm, 1.1 W mm$^{−2}$), applied during tetracene
                      deposition, not only increases grain size but also induces
                      photoalignment. The observed effects arise from enhanced
                      molecular diffusion, resulting from energy transferred by
                      light to the molecules after adsorption, but not from
                      heating the substrate surface underneath. We observe that
                      linearly polarized light promotes photoalignment, while
                      increased crystallite sizes occurs with both linear and
                      circular polarizations. We propose an Ostwald ripening
                      process facilitated by laser illumination, where smaller
                      crystallites get optically heated and dissolve, allowing
                      molecules to surmount step-edge barriers and assemble into
                      larger crystallites. Importantly, the crystallite sizes
                      achieved with laser illumination surpass those attainable by
                      substrate heating alone. The study demonstrates that laser
                      illumination acts as a promising new parameter for
                      controlling thin film properties and is distinct from growth
                      control via substrate temperature and growth rate. Light
                      control also includes the ability for lateral patterning,
                      with implications for the future of molecular materials and
                      their manufacturing technologies.},
