A time-dependent numerical model of a dysprosiumdoped ZBLAN glass fiber is developed in order to design a pulsed laser emitting at about 3μm wavelength, by employing an in-band pumping scheme. A number of design parameters are changed to optimize the laser performance. Gain-switching regime with an output signal peak power close to 59W and a full width at half maximum (FWHM) pulse duration shorter than 184 ns is simulated for a fiber with dopant concentration of 2000 ppm, by employing a pulsed input pump with a peak power of 5W and a repetition rate of 100 kHz at the wavelength of 2.8 μm. These characteristics are very promising and theoretically predict the feasibility of a laser which can find application in many areas such as chemical, biological and environmental monitoring.

Abstract
A time-dependent numerical model of a dysprosiumdoped ZBLAN glass fiber is developed in order to design a pulsed laser emitting at about 3μm wavelength, by employing an in-band pumping scheme. A number of design parameters are changed to optimize the laser performance. Gain-switching regime with an output signal peak power close to 59W and a full width at half maximum (FWHM) pulse duration shorter than 184 ns is simulated for a fiber with dopant concentration of 2000 ppm, by employing a pulsed input pump with a peak power of 5W and a repetition rate of 100 kHz at the wavelength of 2.8 μm. These characteristics are very promising and theoretically predict the feasibility of a laser which can find application in many areas such as chemical, biological and environmental monitoring.File | Dimensione | Formato | |
