Generation and amplification of ultrashort shaped pulses in the visible by a two-stage noncollinear optical parametric process.

ABSTRACT

We report the generation and amplification of ultrashort shaped pulses in the visible by a two-stage noncollinear optical parametric amplification process. Phase and amplitude profiles of the shaped pulses are conserved in our amplification scheme. The energy losses normally associated with the production of complex shaped pulses are eliminated.
