PAM XIAMEN offers YAG( undoped ,Ce-doped,Nd-doped).
Undoped YAG is a substrate material that can be used for UV and IR optics. Sapphire has been the substrate of choice for these applications; however it is difficult to polish Sapphire to a 10-5 scratch-dig [...]
A method for the annealing of a CdZnTe crystal is described in this paper. Pure Cd and Zn metals are used as annealing sources, which simultaneously provide exact Cd and Zn equilibrium partial pressures for CdZnTe at a certain temperature. Characterizations reveal that homogeneity [...]
Gain characteristics and femto-second optical pulse response of 1550 nm-band multi-stacked QD-SOA grown on InP(311)B substrate
In this paper, we demonstrated 155 nm-band multi-stacked QD-SOA grown by the strain-compensation technique on an InP(311)B substrate, and evaluated the fundamental gain characteristics and the femto-second optical pulse response, [...]
