Nonperturbative generation of above-threshold harmonics from pre-excited argon atoms in intense mid-infrared laser fields Download: 570次
Abstract
We experimentally investigate the generation of above-threshold harmonics completely from argon atoms on an excited state using mid-infrared femtosecond laser pulses. The highly nonlinear dependences of the observed signal on the pulse energy and polarization of the probe laser pulses indicate its nonperturbative characteristic.
