We demonstrate negative radiation pressure on gain medium structures, such that light amplification may cause a nanoscale body to be pulled toward a light source. Optically large gain medium structures, such as slabs and spheres, as well as deep subwavelength bodies, may experience this phenomenon. The threshold gain for radiation pressure reversal is obtained analytically for Rayleigh spheres,...

Ultrafast lasers have a crucial function in many fields of science; however, up to now, high-energy pulses directly from compact, efficient and low-power semiconductor lasers are not available. Therefore, we introduce a new approach based on temporal compression of the continuous-wave, wavelength-swept output of Fourier domain mode-locked lasers, where a narrowband optical filter is tuned synch...
a crd experiment was conducted to study three different soybean meals on experimental qualitative properties, digestibility of protein and performance in broiler chickens for a 42 day period. a total of 195 day-old ross 308 male broiler chickens were randomly distributed to 3 dietary treatments with five replicates of 13 chicks each. to measure digestibility of protein, thirty 15-day-old ross 3...
