Control of emission interval and timing in triggered periodic superradiance
Hideaki Hara, Riku Omoto, Noboru Sasao +6
To achieve more controllable development of coherence in solids, we investigated the effect of a trigger laser tuned to the superradiance transition wavelength on periodic superrad…

Periodic super-radiance in Er:YSO crystal
Hideaki Hara, Junseok Han, Yasutaka Imai +5
We observed periodic optical pulses from an Er:YSO crystal during irradiating with an continuous-wave excitation laser. We refer to this new phenomenon as "periodic super-radiance"…

Realization of superabsorption by time reversal of superradiance
Daeho Yang, Seung-hoon Oh, Junseok Han +5
Emission and absorption of light lie at the heart of light-matter interaction. Although emission and absorption rates are regarded as intrinsic properties of atoms and molecules, v…
