We design an experiment to obtain a Bose-Einstein Condensate (BEC) using 87Rb atoms. Taking
advantage of this setup, we develop a simple and efficient method to transfer atoms from a first Magneto-
Optical-Trap(MOT) to a second one. Our system consists of two glass vacuum cells horizontally connected
with a MOT aligned at the center of each cell. Once rubidium atoms are loaded into the first MOT, the
pushig beam forces them to move forward to the second MOT. We use a near-resonant weak laser beam
to make the atoms reach the second cell. MOT1 and MOT2 both run in retroreflected-three beam MOT
configuration.
Nowadays, it has become an essential task to characterize the nonlinear optical response of new materials, in
order to identify suitable candidates for ultrafast processing in all-optical devices. One of the most widely-used
techniques for this purpose is the Z-scan, which consists on measuring the nonlinear refractive and absorptive responses
of a material by scanning the sample along the optical path of a convergent Gaussian beam. We will analyze the
nonlinear response of carbon disulfide and new organic composites. In our setup, using a high-repetition rate
femtosecond laser, we have included an optical chopper for managing thermal effects in order to characterize electronic
nonlinearities.
