In metal sheet processing for automotive application, it is crucial to guarantee high robot dynamics reduced cycle times and adequate components accuracy be competitive in the market. Since two aspects are closely inversely related, problem becomes challenging. After first cutting tests, Cartesian Robot prototype displayed insufficient dimensional when undergoing accelerations. The solution her...

We demonstrate a wavelength-tunable, passively mode-locked erbium-doped fiber laser based on graphene and chirped fiber Bragg grating. The saturable absorber used to enable passive mode-locking in the fiber laser is a section of microfiber covered by graphene film, which allows light-graphene interaction via the evanescent field of the microfiber. The wavelength of the laser can be continuously...

We derive the explicit analytical form of the time-dependent coupling parameter to an external field for perfect absorption of traveling single photon fields with arbitrary temporal profiles by a tunable single input-output open quantum system, which can be realized as either a single qubit or single resonator system. However, the time-dependent coupling parameter for perfect absorption has a s...
