First configuration: Levitation height change of the PyC piece levitated above the magnet when its surface is irradiated by a laser beam (green dashed line). (a) Photograph of a setup with a vibration absorber where the magnet array is guided by way of helical springs and a metal block fixed to the magnet array is immersed in glycerine. (b) Response in terms of displacement after 60 s irradiation at 532 nm for 20 mW and at 1064 nm above 20 mW.
