Infrared Absorption at 10.6 μ in GaAs

The diffuse component of the cosmic X-radiation

The A-2 experiment on HEAO-1 is specifically developed to study the diffuse radiation of the entire X-ray sky over a wide bandwidth, covering both the soft X-ray emission from nearby regions of the galaxy and the isotropic hard X-radiation indicative of remote extragalactic origins. A partial conclusion from the experiment is that a hot thermal plasma, on a scale comparable to that of the universe, may be the principal source of hard X-radiation characteristic of the extragalactic sky. Some key features of this background were defined

Stimulated brillouin scattering in liquids

Stimulated Brillouin scattering of intense laser light with build-up of coherent hypersonic waves in liquid

Solar X-rays scattered by Venus, Mars and the Moon

Scattering process of solar X rays with photoionization fluorescence by planetary atmosphere

Optical frequency waveguide and transmission system Patent

Observation of mode locking and ultrashort optical pulses induced by antisotropic molecular liquids

Mode locking and ultrashort pulses have been produced in a giant-pulse ruby laser with heated nitrobenzene (T > 110°C) or -chloronaphthalene (T > 62°C) inside the optical resonator. 10^(–11)-sec pulses were observed with the two-photon fluorescence technique

Optical waveguiding in proton-implanted GaAs

We have produced optical waveguides in n-type GaAs by implantation with 300-keV protons. The guiding is shown to be due to the elimination of charge carriers from the implanted region. Annealing of the waveguide leads to very large reductions in the 1.15-µ guided-wave absorption
