A movable mass spectroscopy gas sampling apparatus has been established and a straight-line fit ofsilane depletion fraction f is proposed.The spatial density di
One-dimensional photonic crystal of second-order nonlinearity is studied. Among the three waves of the parametric interaction process of down-conversion with a
We realize a stable self-starting passively mode-locking all-solid-state laser by using novel GaAs mirrors as the absorber and output coupler. The GaAs mirror i
