The modulation depth can be tuned in a broad range from sixty six.5% to six.two% by various the thickness of graphene. Our effects counsel that ultrathin graphene films are possibly practical as optical aspects in fiber lasers. Graphene as a laser manner locker might have quite a few deserves for example decreased saturation depth, ultrafast recove… Read More

The calculation earlier mentioned assumes a uniform beam depth profile. You must now take into account hotspots inside the beam or other non-uniform intensity profiles and around calculate a maximum electrical power density.The duration of the SHG crystal substantially impacts the spectral width from the reference pulse, or alternatively the bandwi… Read More
