Theory of non-linear optical effects
Non-linear optical effect in femtosecond laser trapping:
In optical trapping using laser tweezers usually a continuous wave laser is used. When femtosecond pulsed lasers are used the trapping force (and potential) is dramatically modulated by optical nonlinearity.
Can we estimate the force (and potential) under femtosecond pulsed excitation for different particle sizes?
