ABSTRACT
An electro-optic laser beam deflector with a clear optical aperture of 8.6 mm has been designed, realized, and tested. The electro-optic material used to implement the device was a MgO:LiNbO3 crystal. The exceptionally large aperture makes the device suitable for applications where fast scanning of high power laser beams is needed. The measured deflection angle was 120 μrad/kV for a total length of electro-optic material of 90 mm. A mode quality analysis of the laser beam revealed that the M2 of the laser is affected by less than 4% during scan operation when maximum driving voltage is applied.

    In recent years there has been rapid development of ultra-high irradiance lasers. Coincidently, high energy quasi-monoenergetic ultra-short electron bunches have been generated using such lasers in laser-plasma interaction experiments. We show that the combined use of such lasers and electron...

    A venetian style infrared attenuator placed prior to a pinhole spatial filter results in variable high-power laser attenuation. This attenuation scheme has a wide dynamic range, results in high-quality Gaussian beams, does not introduce beam walk-off error, and is independent of polarization.
