摘要: A fluidized mixture is issued from a nozzle comprising a fan jet at the outlet, causing the mixture to spread as it is issued. The issued material is collected on a moving collection surface located a distance of between 0.25 and 13 cm from the outlet of the nozzle, prior to the onset of large scale turbulence in the fluid jet. The resulting product has good basis weight uniformity.

摘要: A laser diode package (1) couples laser diode outputs into a plurality of fibers (21), and these are bundled and brought to an output face (2') that produces a divergent composite beam from the fiber ends (21'). The beam end pumps a solid state laser (100) across a gap (6), and the divergence allows a wide tolerance in alignment of the pump and crystal (3). Preferably, one cavity mirror (7) is a focusing mirror that reconcentrates residual pump light in the desired mode. In a preferred embodiment, the output face of the package is at a short stub (2) or ferrule that provides a simple and effective pump beam centering alignment. The solid state laser (100) may be a rod or crystal (3) and is preferably sufficiently short, in relation to pump beam diameter and divergence in the rod, that the pump beam within the rod lies in the TEM.sub.OO mode volume of the laser cavity. A concave mirror then refocuses residual pump light back into that mode. The rod preferably has a high index at the pump wavelength, but need not have high absorption. A common mounting plate (10) and heat sinking arrangement are provided for the package (1) and crystal (3).

摘要: A laser diode package couples laser diode outputs into a plurality of fibers, and these are bundled and brought to an output face that produces a divergent composite beam from the fiber ends. The beam end pumps a solid-state laser across a gap, and the divergence allows a wide tolerance in alignment of the pump and crystal. Preferably, one cavity mirror is a focusing mirror that reconcentrates residual pump light in the desired mode. In a preferred embodiment, the output face of the package is at a short stub or ferrule that provides a simple and effective pump beam centering alignment. The solid-state laser may be a rod or crystal and is preferably sufficiently short, in relation to pump beam diameter and divergence in the rod, that the pump beam within the rod lies in the TEM.sub.OO mode volume of the laser cavity. A concave mirror then refocuses residual pump light back into that mode. The rod preferably has a high index at the pump wavelength, but need not have high absorption. A common mounting plate and heat sinking arrangement are provided for the package and crystal, and the assembly is relatively insensitive to alignment variations, with only one cavity mirror requiring optical alignment. The bundle packing may take various shapes to match modes of a sheet or rectangular lasing medium.
