| Research Abstract |
The present research aims at proving experimentally the macro-coherent amplification mechanism that is a new class of coherent and cooperative phenomena similar to the super-radiance.
When such an amplification mechanism works for a two-photon deexcitation process, for example, its rate is expected to be amplified. In our experiment, we prepared the vibrational excited states of hydrogen gas by adiabatic Raman scatterings, and observed the two photon cascade process.
As a result we found that the rate of the observed process is amplified as the initial coherence increases and that its amplification factor agrees with the theoretical expectation. We have thus established the validity of macro-coherent amplification mechanism.
