Ultrashort laser pulse characterization techniques

Autor: R. Ortega Martínez

Publikováno v: Optica Pura y Aplicada. 46:39-47

There are several competing techniques for the characterization of ultrashort laser pulses. Here we report the studies that we have done in the laboratory. These techniques use the autocorrelation or cross-correlation of the signals. The spectral pro

High speed femtosecond pulse characterization based on spectral interferometry

Autor: R. Ortega Martínez, J. Garduño Mejía, M. Rosete Aguilar, C.J. Román Moreno, G. Castro-Olvera

Publikováno v: Optica Pura y Aplicada. 46:1-6

In this work, we present spectrum and spectral phase retrieval of femtosecond pulses at 74 Hz refresh rate by a spectral interferometry technique. Different spectral phase designs including high order chirp are measured and generated with a pulse sha

The influence of nutritional risk in elderly patients hospitalized for bone fracture

Autor: M. J. Calero-García, M. D. Calero, A. R. Ortega Martínez, E. Navarro González

Publikováno v: International Archives of Medicine.

Introduction: Bone fractures in older adults involve hospitalization and surgical intervention, aspects that have been related to functional and cognitive impairment. Several variables have been studied as moderators in how these patients evolve, suc

Variation of spatial soliton in liquid crystals due change of polarization of the incident laser beam

Autor: C. J. Román Moreno, A. A. Rodríguez-Rosales, R. Ortega-Martínez

Publikováno v: SPIE Proceedings.

We present experimental evidence obtained in the generation and variation of dark to bright optical spatial solitons due the change of polarization plane of He-Ne laser beam incident in the sample of liquid crystals 5CB doped with methyl red at 0.1%

Observation of the commutation between bright and dark spatial optical solitons

Autor: C. J. Román, R. Ortega-Martínez, A. A. Rodríguez-Rosales, E. Ordoñez, O. Kolokoltsev

Publikováno v: SPIE Proceedings.

We report a new experimental technique on generation of both dark and bright optical spatial solitons in liquid crystals doped with organic dyes. In our recent works we have demonstrated that in some liquid crystals (LC's) the effective nonlinear ref

Publikováno v: Neurocirugia (Asturias, Spain). 18(6)

We report 3 patients with fibrous solitary tumor of meningeal location where we described the histological study, as well as evolution after the surgical treatment. The described patients presented ages of 37, 52 and 65 years, after the resection has

Ultra-short pulse lasers: principles and applications

Autor: H. Cruz, R. Ortega-Martínez, A. A. Rodríguez, M. J. Orozco-Arellanes, C. J. Román

Publikováno v: SPIE Proceedings.

This contribution explains the physics principles of titanium-sapphire laser and the technology used to produce ultra-short pulses of 100 fs, at a 76 MHz rate, 13 nJ energy per pulse with an average power of 1.1 W. The characterisation of the laser p
