Creation of an Ultracold Plasma by Photoionizing Laser-Cooled Caesium Atom

The signals of ultracold plasma are observed by two-photon ionization of laser-cooled atom in a caesium magnetooptical trap. A simple model has been introduced to explain the creation of plasma, and the mechanism is further investigated by changing the energy of a pulsed dye laser and the number of initial cooled atoms.
