| Abstract: | A novel method of ultrafast rotation of ring-shaped op-tical lattice in the picosecond time region was proposed and demonstrated. Our ring-lattice generator was as-sembled by a pair of linearly chirped pulses with time delay, a high-order birefringent retarder, and an axially symmetric polarization element. Using a mode-locked Ti:sapphire laser oscillator as a light source, stable two-, four-, and six-petaled ring-lattice rotations were respec-tively demonstrated with the rotation periods of 1.6 ps, 3.2 ps, and 4.8 ps. Our method has a potential to open up a new technique to resonantly excite propagating quasi-particles together with their coherent enhance-ment. |
