Patent number: 5170406Abstract: An end-pumped laser oscillator having an amplifier including a solid-state gain medium. Pump beams, which are generated by two groups of laser diode bars placed between the optical elements defining the optical resonator, are directed onto opposite end surfaces of the solid-state gain medium, which intersect the optical axis of the optical resonator. The laser diode bars of each group are circumferentially distributed about the optical axis in a uniform pattern and at the same distance along the optical axis from the gain medium. One group of diode bars is located to one side of the gain medium and the other group is located to the other side of the gain medium. Pump beam energy is thereby effectively and efficiently directed onto both end surfaces of the solid-state gain medium from a plurality of laser diode bars allowing the output power produced by the gain medium to be scaled to the thermal limits of the gain medium.Type: GrantFiled: March 13, 1991Date of Patent: December 8, 1992Assignee: Amoco CorporationInventor: Steve C.

Patent number: 5157184Abstract: Catalyzed vapor-phase processes are taught for the oxidative dehydrogenation of a lower-alkyl-monosubstituted ethylbenzene to a lower-alkyl-monosubstituted styrene. Barium pyrophosphate and the pyrophosphate-containing calcination product of KFe.sub.3 H.sub.14 (PO.sub.4).sub.8.nH.sub.2 O, n running between about 1 to about 4, are shown to effectively catalyze these dehydrogenations at a low enough temperature such that very little cracking of the lower alkyl group occurs which gives superior conversions and selectivities to the corresponding styrenes and lengthened catalyst lifetime. An improved method of preparation of KFe.sub.3 H.sub.14 (PO.sub.4).nH.sub.2 O is described as well as the new material which is essentially KFe.sub.3 H.sub.6 (P.sub.2 O.sub.7).sub.4.Type: GrantFiled: August 28, 1989Date of Patent: October 20, 1992Assignee: Amoco CorporationInventors: Mark A.
