Recent progress in developing phased arrays of high-brightness solid-state lasers is summarized. We address the prospects for continued brightness-scaling via a model that extrapolates measured results to large numbers of array elements and provides

The diode array pumped kilowatt laser (DAPKL) has demonstrated more than an order of magnitude increase in brightness and average power for short pulse diode-pumped solid-state lasers since its inception in 1991. Significant advances in component tec

We demonstrate coherent beam combining using a two-dimensionally patterned diffractive optic combining element. Fifteen Yb-doped fiber amplifier beams arranged in a 3×5 array were combined into a single 600 W, M2=1.1 output beam with 68% combining e

A two-dimensionally patterned diffractive optical element (DOE) was used to coherently combine a 3×5 array of fifteen Yb-doped fiber amplifier beams into a 0.6-kW, M2=1.1 output beam.

Although Dr Albert Hyman in New York is believed to have built the first cardiac pacemaker in 1932, he acknowledges Dr Mark Lidwell in Sydney, Australia as having not only built a pacemaker, but also successfully used it to resuscitate a newborn infa

Analytical rate coefficient expressions are derived at low temperatures for the fast reactions of a 2Π molecule with each of a structureless ion, a 2Π molecule, and a 1Π molecule. The procedure, based on classical capture theory, involves perturba

A 1.26-kW, multi-stage Yb fiber MOPA was coherently combined using active polarization and phase control with 94% visibility to a second fiber amplifier, consistent with estimated decoherence effects from fiber nonlinearity, linewidth, and phasing ac

Two significant coherent combining solid state laser systems will be described. One approach uses a fiber optic amplifier array and the other uses 7 tiled slab amplifier chains. The first of these demonstrated very high efficiency and near perfect be

The sequence specificity of DNA damage caused by cis-diamminedichloroplatinum(II) (cisplatin) and four analogues in human (HeLa) cells was studied using Taq DNA polymerase and a linear amplification system. The primer extension is inhibited by the dr
