| 摘 要： | 利用激光标准干涉法诊断了准分子激光(XeCl,308 nm)在YBa_2Cu_3O_(7-σ)超导靶面激励等离子体的电子密度.结果表明在入射激光功率密度为3×10~8W/cm~2,本底真空度为1.33～13.3 Pa的条件下,等离子体电子密度为10~(16)～10~(17)/cm~3.

| Abstract: | The electron density of excimer (XeCl, 308 nm) laser-produced plasma near the surface of Y-Ba-Cu-O target has been diagnosed with laser interferometry. The results show that the electron density is about 1016-1017/cm3 when the laser power density is 3×108 W/cm2 and the background pressure is 1.33-13.3 Pa. |
