3超强激光开辟了崭新的物理学领域和交叉学科激光强度在超强超短脉冲激光与物质作用物理中起主导作用。与激光强度相关的几个常用物理量可由下面公式算出电场:E[V/cm]=27.5I1/2[W/cm2],(1)磁场:B[T]=E[V/m]/c[m/s],(2)压强:P[Pa]=10-6I[W/cm2]/c[m/s],(3)激光聚焦功率密度已达
3 super-laser opened up a new field of physics and interdisciplinary Laser intensity in super-short-pulse laser and material physics play a leading role. Several commonly used physical quantities related to the intensity of laser light can be calculated from the following formula: E [V / cm] = 27.5I1 / 2 [W / cm2], (1) Magnetic field: B [T] = E [V / m] / c [m / s], (2) Pressure: P [Pa] = 10-6I [W / cm2] / c [m / s], (3) The laser focus power density has reached
