Abstract: The fiber optic laser system and associated lasing method amplifies and divides a primary laser signal into a plurality of secondary laser signals. The fiber optic laser system includes a distribution means, such as a distribution module, for dividing a primary laser signal, generated by a master oscillator into a number of secondary laser signals. The distribution module can include amplification means, such as an optical fiber amplifier, for amplifying the primary laser signal and a signal power splitter for dividing the amplified primary laser signal into a number of secondary laser signals. The secondary laser signals can then be further amplified, such as by a power amplification module including another optical fiber amplifier. The secondary laser signals can be recombined to produce a laser output having a power level greater than the predetermined power level of the primary laser signal.

Abstract: A low-density, porous material is prepared by mixing together microballoons and an oligomeric precursor to a polyesterimide polymer. The oligomeric precursor has an initial viscosity sufficiently low that it can flow and wet the microballoons when first heated to a polymerization processing temperature, and thereafter polymerize. Fibers may be controllably incorporated into the material during processing to impart specific properties, and air may be controllably incorporated into the material during processing to further decrease its density.

Abstract: A method and apparatus for determining the progress of a superplastic formation process that uses cumulative gas-mass outflow from a forming part being formed from generally one or more sheets of superplastically formable material, a process that may include selective diffusion bonding of the sheets together. The method includes using the expected initial conditions of the process to determine the gas-mass cumulative exhaust at room temperature and pressure. The method is advantageous over inlet measuring methods where high pressure gas must be measured and any small hole in the system results in large errors.

Abstract: A method of fabricating a structural panel having a predetermined shape features forming an inflatable envelope assembly from at least a pair of superplastically formed and diffusion bonded metallic core sheets. The inflatable envelope assembly can be disposed between first and second metallic face sheets which are generally superplastically formed into the predetermined shape prior to being assembled. Thereafter, the assembled face sheets and the inflatable envelope assembly can be superplastically formed and diffusion bonded to form an integral structure, such as structural panel having a compound curvature. Alternatively, the inflatable envelope assembly can be disposed between a pair of reinforced titanium composite sheets. The reinforced titanium composite sheets can also be joined to adjacent face sheets, such as by welding or diffusion bonding, such that an integral structural panel having the predetermined shape can be readily fabricated.
