The essential goal of that paper(Chin.Phys.Lett.26(2009)124211)was to obtain a 2-μm Tm:YAG laser with short pulse output.A Q-switched technique is used to real
The moving behaviour of two-and three-particles in a pressure-driven flow is studied by the lattice Boltzmann simulation in two dimensions. The time-dependent v
We obtain an exact analytical solution of the Klein-Gordon equation for the equal vector and scalar Rosen-Morse and Eckart potentials as well as the parity-time
