Proposal for a magnesium photoionization laser at 24.7 nm

A system is proposed in which resonantly excited Mg atoms are rapidly photoionized by soft x rays from a laserproduced plasma, causing inversion and superfluorescent laser action at 24.7 nm in Mg II. Calculations show that significant gains should occur when a moderately sized (10-J, 200-psec) 1064-nm pump laser is used.
