The timing performance of the Timepix4 application-specific integrated circuit (ASIC) bump-bonded to a $100\;\mu\textrm{m}$ thick n-on-p silicon sensor is presented. A picosecond pulsed infrared laser was used to generate electron-hole pairs in the silicon bulk in a repeatable fashion, controlling the amount, position and time of the stimulated charge signal.
