| 中文摘要 | self-compression of femtosecond pulses in noble gases with an input power close to the self-focusing threshold has been investigated experimentally and theoretically. it is demonstrated that either multiphoton ionization (mpi) or space time focusing and self-steepening effects can induce pulse shortening, but they predominate at different beam intensities during the propagation. the latter effects play a key role in the final pulse self-compression. by choosing an appropriate focusing parameter, action distance of the space time focusing and self-steepening effects can be lengthened, which can promote a shock pulse structure with a duration as short as two optical cycles. it is also found that, for our calculation cases in which an input pulse power is close to the self-focusing threshold, either group velocity dispersion (gvd) or multiphoton absorption (mpa) has a negligible influence on pulse characteristics in the propagation process. |
