We investigate the molecular beam epitaxy growth of GaSb films on GaAs substrates using compositionally graded GaAsxSb1-x buffer layers. Optimization of GaAsxSb1-x growth parameter is aimed at obtaining high GaSb crys...
The technique of terahertz pulses generated from the photoconductive switches has been applied in the ultrafast electrical pulse metrology recently.A lumped-element theoretical model is established to describe the per...

We propose a diode end-pumped passively mode-locked Nd:Gd0.42Y0.58VO4 (Nd:GdYVO4) laser at 1064 nm using a GaAs absorber grown at low temperature as the output coupler. Stable continuous-wave (CW) mode locking w...
