A 100-fs ultraviolet pulse is compressed to 12 fs using two types of coherent molecular rotations. Precise control of the time delay between the pulse and the molecular rotations reduced sub-pulses in the temporal profile.
We theoretically study possibilities of creating spatial patterns having subwavelength length by using so-called dark states. These dark states are formed via interaction with bichromatic optical fields. Performing experiments in Rb vapor, we experimentally demonstrated spatial patterns that are smaller than the length determined by the diffraction limit of optical system used in the experiment. This...
We use collinear Raman generation in cooled hydrogen and obtain a wide comb of equidistant frequencies spanning over an octave of bandwidth. We adjust the frequencies to be commensurate and observe an f-to-2f interference.
