Investigation of diffractive grating creation in glass by using femtosecond laser pulses [PDF]
مجله علوم و فنون هستهای, 2019 In this paper, the interaction of femtosecond laser pulses with BK7 glass is investigated. A Ti:sapphire femtosecond laser with the chirped pulse amplification is used.

X-ray phase imaging with a grating interferometer.
Optics Express, 2005 Using a high-efficiency grating interferometer for hard X rays (10-30 keV) and a phase-stepping technique, separate radiographs of the phase and absorption profiles of bulk samples can be obtained from a single set of measurements.

Two-dimensional grating magneto-optical trap [PDF]
, 2017 We demonstrate a two-dimensional grating magneto-optical trap (2D GMOT) with a single input cooling laser beam and a planar diffraction grating using $^{87}$Rb. This configuration increases experimental access when compared with a traditional 2D MOT.

Ultra-fast polymer optical fibre Bragg grating inscription for medical devices
Light: Science & Applications, 2017 We report the extraordinary result of rapid fibre Bragg grating inscription in doped polymer optical fibres based on polymethyl methacrylate in only 7 ms, which is two orders of magnitude faster than the inscription times previously reported.

System-performance analysis of optimized gain-switched pulse source employed in 40-and 80-Gb/s OTDM systems [PDF]
, 2007 The development of ultrashort optical pulse sources, exhibiting excellent temporal and spectral profiles, will play a crucial role in the performance of future optical time division multiplexed (OTDM) systems. In this paper, we demonstrate the difference

Interaction between luminance gratings and disparity gratings
Spatial Vision, 2004 It was shown from geometry and photographic measurement that the shading pattern for a sinusoidal corrugated surface of frequency f approximates to a luminance-defined grating of frequency f, 2f or f + 2f in specific relative phase. It was confirmed that a luminance grating modifies the appearance of a suprathreshold stereoscopic corrugated surface ...
