Effect of pulse temporal shape on optical trapping and impulse transfer using ultrashort pulsed lasers

Shane, Janelle C; Mazilu, Michael; Lee, Woei Ming; Dholakia, Kishan


We investigate the effects of pulse duration on optical trapping with high repetition rate ultrashort pulsed lasers, through Lorentz-Mie theory, numerical simulation, and experiment. Optical trapping experiments use a 12 femtosecond duration infrared pulsed laser, with the trapping microscope's temporal dispersive effects measured and corrected using the Multiphoton Intrapulse Interference Phase Scan method. We apply pulse shaping to reproducibly stretch pulse duration by 1.5 orders of...[Show more]
