Two-dimensional optical beam deflector operated by wavelength tuning.
A new method based on an optical delay line structure is proposed for two-dimensional raster optical beam steering. For one-dimensional beam steering, the laser beam to be deflected is split into N co-directional sub-beams of equal intensity with the aid of a plane-parallel plate. These sub-beams experience a relative time delay, which translates into a phase difference, thus forming a phased a...
متن کاملOptical circular deflector with attosecond resolution for ultrashort electron beam
A novel method using high-power laser as a circular deflector is proposed for the measurement of femtosecond (fs) and sub-fs electron beam. In the scheme, the electron beam interacts with a laser pulse operating in a radially polarized doughnut mode (TEM01 ) in a helical undulator, generating angular kicks along the beam in two directions at the same time. The phase difference between the two a...
متن کاملOptical phased-array beam steering controlled by wavelength.
A scheme for optical phased-array beam steering controlled by wavelength is proposed. In this scheme, the optical scanning device consists of arrayed optical waveguides with specific length differences, by which the desired phase slope that results in optical beam steering is formed at the ends of the waveguides and can be changed by varying the optical wavelength. By introducing the concept of...

متن کاملPyroelectric deflector of charged particle beam
A new type deflector of a charged particle beam based on pyroelectric crystals is proposed and demonstrated experimentally. The transverse electric field arises in the gap between two pyroelectric crystals in vacuum because of the pyroelectric effect appearing when a temperature gradient is applied to both crystals. In a proof-of-principle experiment, we demonstrated deflection of a low-energy ...
