Query: Probing Black-Hole Physics in the Laboratory Using High Intensity
  Femtosecond Lasers   It is shown how laboratory experiments performed with high intensity
femtosecond lasers can probe the physics of black holes in the near-horizon
regime. The acceleration generated by the high intensity laser ranging from
$10^{13}$g to more than $10^{18}$g is identified with the gravitational
acceleration at stretched horizons. In the black-hole's asymptotic region, the
stretched-horizon-reflected light shows a measurable universal phase
acceleration of $c^4/4GM$.
