摘要

Ultrahigh power laser pulses delivered by the Alise beamline (26 J, 32 TW pulses) have been sent vertically into the atmosphere. The highly nonlinear propagation of the beam in the air gives rise to more than 400 self-guided filaments. This extremely powerful bundle of laser filaments generates a supercontinuum propagating up to the stratosphere, beyond 20 km. This constitutes the highest power "atmospheric white-light laser" to date. (c) 2007 American Institute of Physics.
