Webapplications, it is necessary to vary grating parameters, such as fill factor and grating height, over certain areas, e.g. in the expansion and outcoupling grating regions. For this purpose, VirtualLab Fusion enables the introduction of smoothly varied grating parameters inside one region, where the desired variation can be configured in very WebThe large (close to unity) filling factor is important in double-clad amplifiers; it allows them to reduce the requirements for the brightness of the pump and to reduce the length of …
