A low-power, LED-based, high-brightness anomaloscope

Color matches made with a Nagel anomaloscope are used in the differentiation of color vision deficiencies. When these color matches are made over a wide range of retinal illuminances, the changes in the color match provide information about the regeneration kinetics and the absorption spectra of the middle- and long-wavelength cone photopigments. These steady-state color matches vary with a var...

High-Power High-Brightness Lasers

High power high brightness diode lasers are gaining more and more interest for applications previously dominated by expensive and inefficient solid-state lasers due to their better efficiency, brightness and compactness. The significant fact about conventional high brightness optical sources is that they exhibit about an order of magnitude higher brightness than broad-area semiconductor lasers....

High Power, High Brightness Proton Accelerators*

Proton accelerators were originally developed for nuclear physics experiments as an alternative to radioactive source or cosmic rays. From the earliest days, the energy of the proton has been the most important design parameter of the accelerator builders. As early proton accelerators one can name the Van de Graaff[2] and Cockcroft-Walton[3] devices. They are electrostatic machines, of which th...

High brightness injector for a high power superconducting rf FEL

We have developed a concept for a high average power FEL which incorporates a superconducting rf linac in an energy recovery configuration to increase the overall efficiency . Our design minimizes space charge effects at low beam energy by using : (1) higher than usual voltages on our grid modulated electrostatic electron gun and (2) pulse widths much longer than usual, from the gun. These puls...

High Reliability of High Power and High Brightness Diode Lasers

We report on continued progress in the development of high power and high brightness single emitter laser diodes from 790 nm to 980 nm for reliable use in industrial and pumping applications. High performance has been demonstrated in nLIGHT’s diode laser technology in this spectral range with corresponding peak electrical-to-optical power conversion efficiency of ~65%. These pumps have been inc...
