We report a compact high power Tm,Ho∶YAG laser nearly at room temperature.The laser-diode side-pumped Tm∶YAG and Tm,Ho∶YAG laser modules are operated in the
On the basis of first-principles density functional calculations,the present study sheds theoretical insight on ultrathin carbon nanotube (UCNT) and hydrogenate
Using first-principles calculations,we investigate the structural,electronic and hydrogenated properties of the hexagonal BC7 sheet.The computed energy bands an
The roles of the exchange interaction between different magnetic ions in the gadolinium gallium gaet Gd3Ga5O12 are systematically investigated.The effective fie
