There is provided a cylindrical valve 20 for placement in the flow path of a singlet-delta oxygen generator 12 that feeds O.sub.2.sup.* to a chemical laser gain medium 14. The feed path 22 includes a sharp 90.degree. bend 24 that causes fluid velocity variations in O.sub.2.sup.* entering the gain medium 14. Integral with the valve 20 is a tubular structure 12 having a partial circumferential radially extending surface 44 fitted with "O" ring for sealing and opening the feed path between the "O.sub.2.sup.* " generator 12 and gain generator 14. A series of vanes 32, 34, 36 disposed in velocity control zones 50, 52, 54 and 56 are integral with the valve 20 for leveling out the velocity variations and controlling the wake formation 58, 59 and 60 in the O.sub.2.sup.* entering the gain generator 14.

[ What is claimed is:] [1.] In an apparatus for controlling the feed of singlet delta oxygen from a singlet delta oxygen generator to a laser gain generator over a non-rectilinear flow path from a first direction to a second direction, said apparatus comprising:a singlet delta oxygen generator;a laser gain generator;a feed line communicating with said singlet delta oxygen generator with the laser gain generator; andvalve means interposed in said feed line for controlling the feed of said singlet delta oxygen to the laser gain generator, including fluid flow control means for controlling the variation in the velocity of the fluid as it proceeds from said first direction to said second direction, said fluid flow control means comprising a series of vanes disposed in the path of the singlet-delta oxygen for maintaining a uniform rate of flow throughout the cross section of the feed line and arranged to minimize the wake formation from the vanes as the singlet-delta oxygen enters said laser gain generator as the fluid changes direction.
