摘要:

本文深入研究了强电磁场作用下真空对产生的共振多光子近似的两能级理论的某些方面。数值计算强烈表明,一个可行的实验验证这种方法使用现代光学激光技术可以实现。结果表明,在目前可用的激光强度范围内使用高次谐波可以导致多光子过程,每次激光发射可提供高达10^12对。最后,从电场强度和所产生的电子对的能谱的容许值的角度,考察了这种近似的适用范围。

英文摘要:

We present an indepth investigation of certain aspects of the two level on resonant multiphoton approximation to pair production from vacuum in the presence of strong electromagnetic fields. Numerical computations strongly suggest that a viable experimental verification of this approach using modern optical laser technology can be achieved. It is shown that use of higher harmonic within the presently available range of laser intensities can lead to multiphoton processes offering up to 10^12 pairs per laser shot. Finally the range of applicability of this approximation is examined from the point of view of admissible values of electric field strength and energy spectrum of the created pairs.
