Geometry-dependent spectra and coherent-transient measurement of nearly degenerate four-wave mixing using two-photon resonance
Hideaki Hara, Yuki Miyamoto, Takahiro Hiraki +7
We study nearly degenerate four-wave mixing using a two-photon-allowed vibrational transition of parahydrogen. A signal photon is generated by a trigger photon and coherence among…

Coherent two-photon emission from hydrogen molecules excited by counter-propagating laser pulses
Takahiro Hiraki, Hideaki Hara, Yuki Miyamoto +7
We observed two-photon emission signals from the first vibrationally excited state of parahydrogen gas excited coherently by counter-propagating laser pulses. A single narrow-linew…
