Abstract: A method for manufacturing a glass composition including a host glass, a 3p component having a concentration of about 5 mole percent to about 10 mole percent, and at least one of a 6p component having a concentration of about 1 mole percent to about 5 mole percent and a 5p component having a concentration of about 1 mole percent to about 5 mole percent, is provided. The method includes heating the host glass to a first predetermined temperature for a first period of time; mixing a powder including the 3p component and the at least one of the 5p component and the 6p component with the heated host glass into a glass/powder mixture; heating the glass/powder mixture to a second predetermined temperature for a second period of time; and cooling, after heating, the glass/powder mixture.

Abstract: A glass composition for use as a laser medium, a method for producing the glass composition, and a laser apparatus including the glass composition are provided. The glass composition includes a host glass; a 3p component having a concentration of about 5 mole percent to about 10 mole percent; and at least one of a 6p component having a concentration of about 1 mole percent to about 5 mole percent and a 5p component having a concentration of about 1 mole percent to about 5 mole percent.

Abstract: A laser medium includes a single crystal of chromium-doped LiScl-xInxGe1-ySiyO4, where 0?x?1 and 0?y?1. Preferably, x and y are not both 0. A laser, such as a tunable near infrared laser, can contain the laser medium.

Abstract: The apparatus is intended for processing partly solidified slags transported in ladles out of smelting shop and also for processing slags directly besides blast furnaces and steel-making units (e.g. converters).The apparatus comprises a settling bin provided at its inlet with a water-jet granulator. The settling bin incorporates an elevator with perforated buckets for discharging granulated slag. Elevator pulley shafts are located above the level of water in the bin, the head pulley (the furthest from the granulating compartment) is placed higher than the tail pulley (the nearest to the granulating compartment). A drier is provided at the place of discharge of granulated slag from the settling bin.The settling bin is of a sealed design and is divided by a partition into two compartments, one of which is intended for granulating molten slag, and the other, for discharging granulated slag from the bin by the elevator. A constant level of water in the bin is ensured by an overflow partition.
