超强超短激光驱动的伽马辐射
Gamma radiation driven by ultra-intense and ultra-short lasers
摘要
Abstract
Gamma rays,as electromagnetic waves with extremely high energy and exceptional penetrating power,play an irreplaceable role in numerous frontier fields including nuclear physics,astrophysics,high-energy physics,healthcare,and materials science.Advancements in ultra-intense,ultra-short laser technology have enabled breakthrough progress in laser-driven novel gamma-ray sources.Schemes based on laser-plasma interactions can generate high-brightness,collimated femtosecond-scale ultra-short pulse gamma rays,while also exhibiting significant advantages in compact device design.This paper systematically analyzes the physical mechanisms of laser-driven gamma radiation in the range of hundreds of keV to tens of MeV.It focuses on the characteristics of three primary generation mechanisms:inverse Compton scattering,bremsstrahlung,and betatron radiation.The paper reviews major research advances in China within this field and diagnostic techniques.Research indicates that by optimizing laser-matter interaction parameters,the brightness,pulse width,and energy spectrum characteristics of gamma rays can be effectively controlled.关键词
