产生波长小于一埃的激光将有许多重要的应用。自从穆斯堡尔效应被发现以来，人们已经意识到，如果我们能够制备激光所依赖的布居反转，我们就能够激发适合于这种范围内的激光的核跃迁，而且人们早就知道，在布居反转状态下，一些核异构体是可以产生的。那么，为什么我们还没有任何运行中的伽马射线激光呢？
Lasers generating wavelengths shorter than one angstrom unit would have many important applications. Ever since the discovery of the Mossbauer effect it has been realized that we would be able to stimulate nuclear transitions suitable for lasers in this range if we could prepare the population inversion on which lasers depend, and it has also long been known that some nuclear isomers are producible in a state of population inversion. Why then do we not yet have any operating gamma‐ray lasers?
