The study of the pulse laser properties in two different photonic crystal fiber materials

الملخص EN

This study is to obtain a better understanding of how to shape the pulse laser spectrum by varying the material properties of the photonic crystal fiber (PCF).

This includes the ability to obtain spectral power in particular wavelength regions, and obtaining a broad bandwidth..

Numerical modeling of the split step Adaptive Fourier method has been used to solving a form of nonlinear Schrödinger equation, which describes the propagation of pulses in PCF.

It was investigated how the spectrum can be controlled through dispersion property.

The electromagnetic wave that send from IR laser diode source through the PCF to the observer.

the optical properties of this electromagnetic wave, normalized power, intensity, dispersion, and group delay dispersion will be studied for the input, output and observer laser pulse.

The compared of the different two materials of PCF (fused silica and Barium-fluoride BaF2) that be usedand studies.
