large number of applications in physics, chemistry, bilogy, and engineering would greatly benefit from a laser eam that had a sharp focus but, simultaneously, a negliible spreading due to diffraction. Examples of such aplications include laser drilling and writing, trapping nd guiding of microparticles or nanoparticles and neural atoms, precise alignment and metrology echniques, and high-resolu...
Remote sensing applications often require high energy laser-like beams with narrow bandwidth and low divergence at wavelengths that cannot be reached directly with ordinary laser materials. The common way of generating such wavelengths is through optical parametric oscillators (OPOs), sumor difference frequency generators, or a combination of these. For the new beam to be generated with high co...
The CESR Luminosity Upgrade Plan consists of several consecutive steps, or phases [1]. At the present time, this program is in Phase II. The next step, Phase III, would yield a luminosity of 1x1033cm-2sec-1 with 45 bunches in each beam for a total current of 1 A. This plan utilizes four superconducting single-cell cavities with an accelerating gradient of 6 MV/m, which corresponds to a peak acc...
