We present the first reported observation in the infrared of nonlinear phase-conjugated reflection. This was achieved via degenerate four-wave mixing in polycrystalline germanium. The observation was facilitated by taking advantage of the counterprop

We demonstrate a 42 channel, low distortion, high link budget 1.55 micrometers lightwave AM- VSB CATV transport system based on modulated laser and erbium doped fiber amplifier. The link budget is enhanced by 21 db by the erbium doped fiber amplifier

This paper discusses the possibilities of using certain constant-weight block codes in optical data links and in optical ring networks. The codes that appear to be particulary attractive have exactly as many 1s as 0s in each code word, so there is no

A technique for measuring the high‐voltage transients associated with low inductance, pulsed gas discharges is described. Measurements are made directly at the 10‐kV level with a transmission line Kerr cell and narrow‐width, pulsed dye laser, s

A new type of beam splitter is described, which is capable of producing a division of light in a polarization independent manner. Typical beam splitters (used off-axis) have a pronounced polarization dependence. The device is a thin plate of suitably

The interaction of 6328‐A laser radiation with excited atoms in a He‐Ne gas discharge leads to a sizeable change in the population of the 3s2 and 2p4 levels of Ne. Population of levels connected to the upper and lower laser levels through radiati

The expansion of the shock front of a laser‐triggered, atmospheric air spark was studied by shadow photography with a transversely excited atmospheric UV nitrogen laser. It was found that the shock front of the short spark (0.5 mm) was cylindrical.

A technique is described to couple and synchronize two transversely excited atmospheric (TEA) nitrogen lasers in an oscillator‐amplifier configuration to obtain spatially coherent 1‐nsec pulses at 337 nm with an energy/pulse of several hundred mi
