Waveform control of three kinds of chirped pulses (i.e. βt, βt 2 and βt 3) to produce harmonic spectra and attosecond pulses has been investigated. It is found that by properly choosing the chirps, the chirp delays and the other laser parameters,

The effect of nonlinear chirp combination on the enhancement of harmonic cutoff and harmonic intensity has been investigated by using a two-color chirped pulse. It is found that with the combination of 2-order chirp form, the strongest intensity enha

We investigate the pulse duration dependence of harmonic yield in isotopic molecules of H2+ and T2+ driven by different laser intensities. Generally, the harmonic yield can be improved as pulse duration increases and then a maximum value can be obtai

Nitrogenated holey graphene (NHG) has attracted much attention because of its semiconducting properties. However, the stacking orders and defect properties have not been investigated. In this letter, the structural and stacking properties of NHG are

A potential scheme to obtain the optimal improvement of high harmonic spectra has been proposed by using the fixed intensity chirped combined pulse. It shows that with the introduction of two-color, three-color and four-color chirps, not only the har

The CASTEP calculations based on the density function theory (DFT) have been carried out in studying magnetic properties of C-doped ZnO crystal. The long-range ferromagnetism (FM) can be attributed to coupling between C energy levels. We also investi

We calculate stress in YBa 2 Cu 3 O 7− x /MgO (YBCO/MgO) and YBa 2 Cu 3 O 7− x /LaAlO 3 (YBCO/LAO) by XRD of the sample, σ 1 = −1.2 GPa and σ 2 = −1.4 GPa, respectively, which shows that the stress in YBCO/LAO is stronger than that in YBCO/
