Usually the temperature in a Bose-Einstein condensate is experimentally deduced resorting to the comparison between the Maxwell-Boltzmann velocity distribution function and the density profile in momentum space. Though a successful method it is merely an approximation, since it also implies the use of classical statistical mechanics at temperatures close to the condensation temperature where quantum effects play a relevant role and cannot be neglected. The present work puts forward an alternative method in which we use an ultra-intense light pulse and a nonlinear optical material as detectors for differences in times-of-flight, and in this way the temperature is deduced.
