We demonstrate a Fe∶ZnSe laser gain-switched by a 2.9μm ZnGeP2 optical parametric oscillator under pulse repetition frequency of 1 kHz at liquid nitrogen temp
We study systematically the period-doubled Bloch states for a weakly interacting Bose-Einstein condensate in a one-dimensional optical lattice.This kind of stat
As a crucial parameter for a few-cycle laser pulse,the carrier envelope phase (CEP) substantially determines the laser waveform.We propose a method to directly
Ti3AlC2 samples are irradiated in advance by 3.5 MeV Fe-ion to the fluence of 1.0× 1016 ion/cm2,and then are implanted by 500 keV He-ion with the fluence of 1.
The hydrogenation of two-dimensional (2D) systems can efficiently modify the physical and chemical properties of materials.Here we report a systematic study on
