Doubly excited autoionizing states in barium of the configuration 6p/sub 3/2/np (n greater than or equal to 12) are shown to decay preferentially to yield the 6p/sub 1/2/ excited state of Ba/sup +/. The resulting population inversion is used to produce amplified spontaneous emission at 493 nm and 650 nm corresponding to the 6p/sub 1/2/ - 6s/sub 1/2/ and 6p/sub 1/2/ and 6p/sub 1/2/ - 5d/sub 3/2/ transitions in Ba/sup +/. Under appropriate conditions, strong coherent output at 167 nm was simultaneously produced and could be attributed to a four-wave parametric process in the excited Ba/sup +/. This principle of selective autoionization is expected to be applicable to the construction of a new class of ion lasers extending into the vacuum-ultraviolet wavelength region.
