Numerical simulation of a gradient-index fibre probe and its properties of light propagation

“…In recent years, there have been a few theoretical articles dealing with the self-focusing performance of the gradient-index material, [11,12] the propagation property of the Gaussian beam, [13,14] the imaging quality enhancement of the optical coherence tomography, [15] etc. In addition, Jung et al [16] reported a numerical analysis of the gradient-index lens based optical probe.…”

Propagation properties of the pulsed hollow Gaussian beam through a circular aperture

“…Because of the mathematical difficulty in dealing with the propagation of ultrashort pulsed beams with constant waist width, usually numerical results or approximate propagation expressions are found in the past studies. Beyond these, there are few studies focused on the diffraction of pulsed beam from the hard edges [9][10][11].…”
