“…In this Section, we will intrinsically explore fibre-optical tuning methods that do not use the mechanisms presented in Figure 2. It is shown in [121] that non-linear effects in a mode-locked fibre laser with a semiconductor optical amplifier (SOA) as the active medium may induce significant (tens of nanometres) changes in the output wavelength despite the presence of a spectral filter in the cavity. Without a spectral filter, SOA may shift the wavelength of short pulses to shorter wavelengths by up to 20 nm [122].…”

Methods of output wavelength tuning in short-pulsed fibre lasers are analysed. Many of them rely on spectral selection principles long used in other types of lasers. For compatibility with the fibre-optical format, the corresponding elements are sealed in compact, airtight volumes with fibre-optical radiation input and output. A conclusion is presented about the relatively small number of inherently “fibre-optical” ways of tuning the wavelength of radiation. It is demonstrated that the range of output wavelength tuning in short-pulsed fibre lasers may span hundreds of nanometres (even without extension beyond the active medium gain contour through nonlinear effects). From the presented review results, it may be concluded that the search for the optimal tuning method complying with the user-preferred all-PM-fibre short-pulsed laser design is not yet complete.

“…This theory can be extended to include semiconductor lasers if the lasers have two energy levels, one of which is represented by the valence beam and the other of which is represented by the conduction beam. If the semiconductor lasers have two energy levels, this theory can be expanded to include semiconductor lasers [24], [25].…”

The behavior of the optical pulse release was investigated during chirped pulses amplification, which consisted of two chirped fiber Bragg grating and one semiconductor optical amplifier (SOA). This occurred when the pulse width, << carrier lifetime , as well as the effect of the length parameter on the shape and spectrum of the electric field, intensity, and phase of amplified pulses, were taken into consideration. The purpose of this research is to investigate the effect of release length on the temporal electric field laser amplifier while simultaneously generating optical pulses with the help of a mode-locked laser system semiconductor. In the scenario where τp and τc are taken into account, we discovered that the length of the release has a significant impact on the modes of the phase and the electric field.
