The detailed home-built PiP experimental setup demonstration and actual processing video (VIDEO)
Caption
A femtosecond laser beam is reflected by a high-speed rotating polygon mirror and then focused on the sample. The setup owns a laser scanning speed greater than 36 m s-1 in a working range of 300 mm, with a stage movement speed faster than 1.5 mm s-1, which ensures to anneal a 5 cm × 5 cm sample in 30 s and a 10 cm × 10 cm sample in 60 s.
