title: Analysis of lens and zone plate combinations for achromatic focusing of ultrashort laser pulses.
abstract: Analysis of a combination zone plate and lens system is presented for the design of optical systems to focus ultrashort laser pulses. A system design that is free of propagation-time delay distortion and chromatic aberration is presented.
