This seminor gives an introduction on the measurement of the Hawking radiation by ultra-intense laser pulses in laboratory (Belgiorno et.al. 2010). The laser pulses induce a refractive index perturbation (RIP) in fused silica. Photons in RIP region suffer a large acceleration, which may create an event horizon similar to gravity system. The Hawking radiations of the event horizon are observed in experiment in terms of the Bessel-X beam. The experiment results match with theoretical prediction qualitatively.
