Highly crystalline epitaxial Ba<inf>0.8</inf>Sr<inf>0.2</inf>TiO<inf>3</inf> (BST) thin-films are grown on (001)-oriented LaNiO<inf>3</inf>-buffered LaAlO<inf>3</inf> substrates by pulsed laser irradiation of solution derived barium-zirconium-titanium precursor layers using a UV Nd:YAG laser source at atmospheric conditions. The structural analyses of the obtained films, studied by X-ray diffractometry and transmission electron microscopy, demonstrate that laser processing allows the growth of tens of nm-thick BST epitaxial films with crystalline structure similar to that of films obtained through conventional thermal annealing methods. However, the fast pulsed nature of the laser employed leads to crystallization kinetic evolution orders of magnitude faster than in thermal treatments. The combination of specific photothermal and photochemical mechanisms is the main responsible for the ultrafast epitaxial laser-induced crystallization. Piezoresponse microscopy measurements demonstrate equivalent ferroelectric behavior in laser and thermally annealed films, being the piezoelectric constant ∼25 pm V<sup>-1</sup>.This work was financed by the Ministry of Economy and Competitiveness under the Project Nos. MAT2011-28874-C02-01, ENE2014-56109-C3-3-R, and MAT2014-51778-C2-1-R and Consolider Nanoselect CSD2007-00041 by Generalitat de Catalunya (2009 SGR 770, 2014 SGR 753 and Xarmae) and by the Spanish National Research Council under the Contract No. 200960I015. A.Q. and M.d.l.M. are also grateful for JAE-Predoc fellowship and European Social Fund program.
