| Research Abstract |
We developed an all-optical ultrafast magnetic-resonance method with using femtosecond optical pulses but without using microwave, achieved high time resolution and broad-band response, and applied it to the study of ultrafast magnetic phenomena in the excited triplet states of organic molecules and antiferromagnetic materials. We demonstrated optical manipulation of spin coherence such as phase control of spin precession and pure spin rotation about an arbitrary axis, and showed that it is possible to carry out all-optical ultrafast manipulation of spins.
