Investigation on the self-starting Mamyshev oscillator with low threshold
Wei Guo, Sihua Lu, Qiurun He +4
We have demonstrated a mode-locked Mamyshev oscillator based on a single-mode-fibre configuration with low threshould. The influences of spectral filters and the pump power on the…
Bulk vortices and half-vortex surface modes in parity-time-symmetric media
Huagang Li, Xing Zhu, Zhiwei Shi +3
We demonstrate that in-bulk vortex localized modes, and their surface half-vortex ("horseshoe") counterparts self-trap in two-dimensional (2D) nonlinear optical systems with $\math…
Surface solitons in PT symmetric potentials
Huagang Li, Zhiwei Shi, Xiujuan jiang +2
We investigate light beam propagation along the interface between linear and nonlinear media with parity-time PT symmetry, and derive an equation governing the beam propagation. A…
Femtosecond Laser-induced Crystallization of Amorphous Sb2Te3 film and Coherent Phonon Spectroscopy Characterization and Optical Injection of Electron Spins
Simian Li, Huan Huang, Weiling Zhu +7
A femtosecond laser-irradiated crystallizing technique is tried to convert amorphous Sb2Te3 film into crystalline film. Sensitive coherent phonon spectroscopy (CPS) is used to moni…
Improved time-resolved magneto-optical Kerr effect technique and dynamic magnetization reversal mechanism of perpendicularly magnetized FePt films
X. D. Liu, Z. Xu, R. X. Gao +4
The dynamic coercivity cannot be measured rigorously by the conventional time-resolved magneto-optical Kerr effect technique because the irreversible deviation of the transient mag…
Density dependence of spin relaxation in GaAs quantum well at room temperature
L. H. Teng, P. Zhang, T. S. Lai +1
Carrier density dependence of electron spin relaxation in an intrinsic GaAs quantum well is investigated at room temperature using time-resolved circularly polarized pump-probe spe…
