X-Ray and γ-Ray Lasers
The x-ray laser talks heard so far have concentrated on the problem of producing lasing action in the region 1000 A° > λ > 10 A°. Since this region is the one for which experimental demonstrations of lasing are most likely in the near future it is, of course, proper that most work on x-ray lasers concentrate on this regime. In this talk, however, I will look a little further off in the future and discuss the prospects for producing coherent radiation at wavelengths λ < 10A°. Since coherent radiation is most easily produced by producing a population inversion between discrete levels of a radiator, it is most natural to think of generating short wavelength coherent radiation by means of an x-ray laser (XRL) using innershell atomic transitions or a γ-ray laser (γRL) using transitions between discrete levels of nuclei.
