چکیده
Cylindrical density depressions generated by femtosecond laser pulses filamenting in air for different energy depositions is investigated numerically, using a set of hydrodynamic equations. The evolution profile calculated temperature elevations, the results indicate that gas hole getting shallower and wider with increasing elevations. A simulation propagation inside low-density channel implies new way to generate type bottle beam.

Generation of supercontinuum bottle beam using an axicon.
A supercontinuum bottle beam was successfully produced by focusing a supercontinuum laser beam after passing through an axicon. The supercontinuum radiation was generated from a microstructured fiber pumped by a self-kerr-lens mode-locked femtosecond Ti:sapphire laser. The cross-section intensity distributions of the generated bottle were recorded by a beam profiler. Using the line filters to s...
متن کاملChannel Coding using Low Density Parity Check Codes in AWGN
Forward error correction codes (FEC) are used for error detection and correction in communication systems. Low density parity check code (LDPC) is used as a powerful Forward Error Correction code in long distance communication systems which works close to the Shannon limit. Unlike other conventional channel code, the decoding algorithm used for LDPC codes is an iterative message passing algorit...
متن کاملBottle beam from a bare laser for single-beam trapping.
We demonstrate that a laser beam converging from a specific transverse mode is a bottle beam, as described in J. Opt. Soc. Am. B 20, 1220 (2003). To our knowledge, this is the first time that a bottle beam has been generated directly from a laser. By calculating the radiation forces on a dielectric Rayleigh sphere in the bottle beam, we show that the single beam can trap high-refractive-index p...
متن کاملDetection of low Intraperitoneal Air
Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intrapritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...
متن کاملGeneration of two-dimensional plasmonic bottle beams.
By analogy to the three dimensional optical bottle beam, we introduce the plasmonic bottle beam: a two dimensional surface wave which features a lattice of plasmonic bottles, i.e. alternating regions of bright focii surrounded by low intensities. The two-dimensional bottle beam is created by the interference of a non-diffracting beam, a cosine-Gaussian beam, and a plane wave, thus giving rise t...
