| 1 | Picosecond and femtosecond laser induced darking in some optical glass were studied. | |
| 2 | In our 1969 discovery of the SC, Shapiro and I used picosecond pulses with an energy of a millijoule. | |
| 3 | NMR was also used to study dynamic properties of protein both in pico- second to nanosecond and in micro - second to mill - second time scales. | |
| 4 | In this paper, numerical simulation for temperature field of femtosecond-picosecond pulse laser ablation on metal surface is performed by finite-difference method (FDM). | |
| 5 | The research direction and content of this article is based on the NSFC project -the development of picosecond time-correlated single photon counting (TCSPC) spectrometer. |
