Methods for Obtaining Laser Action at Wavelengths Shorter than 3000 A

摘要

The objective of this work is to obtain an ultraviolet source using Cerenkov radiation. Both the spontaneous and stimulated Cerenkov effects are studied theoretically and experimentally, to determine their feasibility as uv sources. From a classical analysis of the spontaneous Cerenkov effect a brightness formula is derived for a relativistic electron beam moving through a dielectric of finite thickness and sufferint no collisions. The analysis is extended to include the effects of coulomb scattering from electron-atom collisions. The stimulated Cerenkov effect is analyzed classically from the Boltzmann and wave equations. The calculation follows the TWT (Traveling Wave Tube) analysis. From the analysis an experimental device was designed using a quartz Fabry-Perot resonator. (Author)
