Symmetry-Based Selective Femtosecond Coherent Control of Transient Two-Photon Absorption
Andrey Gandman, Leonid Rybak, Michal Bronstein +2
We present and implement a new scheme for independent control of both the final and the transient population utilizing the symmetry properties of the system. By proper pulse shapin…

Studies of collisional dephasing of two-photon excited atomic sodium
Leonid Rybak, Lev Chuntonov, Andrey Gandman +2
Coherence relaxation in Na vapor was studied utilizing a pump-probe method with femtosecond pulses. The coherence was created by the pump pulse, which excited the Na atoms to the 4…

Multiphoton Femtosecond Control of Resonance-Mediated Generation of Short-Wavelength Coherent Broadband Radiation
Leonid Rybak, Lev Chuntonov, Andrey Gandman +2
We introduce a new scheme for generating short-wavelength coherent broadband radiation with well-controlled spectral characteristics. It is based on shaping long-wavelength femtose…
