| 1 | And chalcogenide allows for "femtosecond response time" (now that's fast). | |
| 2 | A new method, temporal filtering, is proposed for improving quality of femtosecond laser pulse. | |
| 3 | Surprisingly, this quantum beating lasted the entire 660 femtoseconds. | |
| 4 | The birefringent interference filter for broad-bandwidth femtosecond pulse is investigated theoretically and experimentally. | |
| 5 | This indicates that the spatial alignment and reorientation of molecule in laser field has occurred. |
