摘要

A special-velocity-matched electro-optic (EO) phase modulator employing a microwave resonant design in lithium niobate is presented.Both the microwave property and phase-modulation performances of the 3.25-GHz modulator agree well with the numerical simulations.Using this modulator in a single-pass configuration with 1-kW microwave drive power,the spectral bandwidth of a 1053-nm,3-ns pulse-length laser is broadened to 0.13 nm.With a clear aperture of 5×5 (mm),the modulator is suited for twodimensional smoothing by spectral dispersion in high power laser systems.
