Previous studies on gas/vapor separations using polymeric membrane contactors have always been accompanied with a membrane stability issue: either a wetting phenomenon or a membrane degradation ...

We have developed successfully centimeters long Nd:YAG ceramic fibers by using an advanced ceramic technology. Laser oscillation was performed for the first time with the centimeters long Nd:YAG ...

The characteristics of laser beam by the compensation of thermal lensing effect in a fiber- coupled laser-diode ceramic Nd:YAG laser was investigated. Using a compensator, the divergence and M of the ...
