It's worth noting that 'paper' is from Lydon Larouche's 'Executive Intelligence Review'. Not what I would consider a reliable source even in 1986 the same year he was arrested for credit card fraud. He was subsequently convicted in 1988. As to the content a gamma ray laser is a fun idea but if there were any of them in "as little as three years" and if they had applications then those have remained secret for quite some time. Every public indication is that there aren't any. See here for a discussion: https://en.wikipedia.org/wiki/Gamma-ray_laser https://en.wikipedia.org/wiki/Gamma-ray_laser
