We report our recent progress of investigations on InGaN-based blue-violet laser diodes(LDs).The roomtemperature (RT)cw operation lifetime of LDs has extended t
The heat conduction in a one-dimensional (1D) hard-point model with mass gradient is studied. Using numerical simulation, we find an asymmetric heat conduction
We experimentally investigate the laser characteristics of a ser/es of short pieces of newly-developed Er3+/Yb3+ codoped single mode phosphate glass fibres via
We study the Casimir force between two pistons under different boundary conditions inside an infinite cylinder with arbitrary cross section.It is found that the
A super thin elastic rod is modeled with a background of DNA super coiling structure, and its dynamics is discussed based on the Jourdain variation. The cross s
