    • Intracavity optical trapping with ytterbium doped fiber 

      Laser, R.; Sayed, R.; Kalantarifard, Fatemeh; Elahi P.; İlday, F. Ömer; Volpe, Giovanni; Marago O.M. (SPIE, 2013)
      We propose a novel approach for trapping micron-sized particles and living cells based on optical feedback. This approach can be implemented at low numerical aperture (NA=0.5, 20X) and long working distance. In this ...
    • Optical feedback radiation forces: Intracavity optical trapping with feedback-locked diode lasers 

      Tuna, Yazgan; Sayed, R.; Donato, M.G.; Gucciardi P.G.; Maragò O.M.; Volpe, Giovanni (Optical Society of America, 2012)
      We demonstrate a novel mechanism for optical tweezing, where a trapped particle dynamically alters an external cavity quality factor, reduceing the average intensity and photodamage, even employing low-numerical aperture ...
