We experimentally demonstrate dissipative soliton resonance effect in a 173-m long passively mode-locked figure-eight thulium doped fiber laser with a net anomalous dispersion. The duration of the wave-breaking-free pulse broadens with the increase o

Nonlinear phase contrast microscopy is an optical technique that uses an intensity-dependent refractive index material to produce high-contrasted images of transparent specimens. Earlier proposal of liquid crystals as phase filters for phase contrast

Flow visualization refers to a method used for qualitatively obtain information in the field of fluid mechanics. In this work, we show a simple single lens system using laser light illumination to observe flow dynamics using a setup similar to the sc

We started our study with a group of Mexican Males with an Uncorrected Visual Acuity (UCVA) of 20/20, 20/30, and 20/40. The data was obtained using a Nidek OPD Scan ARK 10000 with the Version 1.11b of the working software. With the resulting Zernike

In this work, we show a simple single lens system using laser light illumination to observe flow dynamics. It is based on a phase contrast technique in which the filter is made of a nonlinear optical material, therefore it is self-aligned and depends

The nonlinear common path interferometer is a simple and robust single lens optical processor using an intensity dependent medium placed on its geometrical focal plane to observe deformed wavefronts. It is described either as a nonlinear inteferomete

An analysis of the image fill factor effect on Zernike-type phase contrast filtering is presented. We define image fill factor as the ratio of the object support area over the illuminating area. Numerical simulations are presented for binary phase ob

In this paper we show numerically and experimentally the generation of ring dark spatial solitons using a phase disk and an opaque ring. In the first case one dark ring is generated and in the second a pair. The propagation and stability of this soli

We modify the double-phase holographic code to implement arbitrary complex modulation with a transmission type twisted-nematic liquid crystal display. This device is employed in the mostly phase configuration, for which the phase modulation is couple
