Research Abstract |
We developed an all-optical ultrafast magnetic-resonance method with using femtosecond optical pulses but without using microwave. We observed optically induced spin precession and spin echoes and demonstrated the optical manipulation of spin coherence in rare-earth ions in crystals. We also generated the fictitious magnetic field using the light-shift effect and demonstrated the phase control of spin precession and the pure spin rotation about an arbitrary axis.
