Experiment and simulation of high power diode lasers reveals a longitudinally-varying current density profile, due to spatial hole-burning. Current crowding at the front facet increases with cavity length and bias, and limits the achievable power.

The output power of modern 975 nm GaAs-based broad area diode lasers is limited by increasing carrier and photon losses at high bias. We use experiment and one-dimensional calculations on these devices to reveal that higher current densities (and hen

This paper discusses the reduction in the applied drawbar force required to penetrate soil with vibrating plows. Harmonically forced linear and orbital motions of a plow blade are investigated. A rigid blade, vibrating with constant amplitude and a t

The mechanical features of a preliminary concept for an open cassegrain antenna are discussed briefly. In the analysis, emphasis is given to the upper rotating structure, where the major problems are the provision for an efficient back-up structure f

The special theory of relativity is used to analyze the motion of plane shock waves in a medium whose equation of state is u = 3 p , u being the mass density and p the pressure. The appropriate conservation equations together with this pressure-densi

Mathematical models relating the gain, cost, diameter, frequency, and rms surface tolerance of ground antennas are developed for both exposed and radome-enclosed parabolic reflectors. Diameters considered range from 15 to 500 feet, while frequencies
