掺镱类激光晶体由于具有大的受激发射截面和长的上能级寿命 ,近年来被人们普遍看好为未来激光惯性约束核聚变研究所需要的首选激光材料。掺镱的氟磷酸钙 [Yb:Ca5( PO4) 3F,简称 Yb:FAP]晶体的发射截面为 5 .9× 1 0 - 2 0 cm2 ,上能级寿命为 1 .0 8ms,因此特别适合作高能量激光
Due to its large stimulated emission cross section and long upper level lifetime, the Yb-doped laser crystals are generally favored in recent years as the laser material of choice for future laser inertial confinement fusion studies. Ytterbium-doped fluorophosphate [Yb: Ca5 (PO4) 3F, abbreviation Yb: FAP] has an emission cross section of 5.9x10-2.0 cm2 and an upper level lifetime of 1.08 ms, making it particularly suitable High-energy laser
