The authors developed an efficient electrooptic phase modulator for deep microwave modulation to control temporal coherence of laser light. Deep modulation was achieved by quasi-velocity-matching between modulation microwave and light with periodic domain inversion of a bulk electrooptic crystal. The interaction length is only limited by a diffraction loss in the bulk modulator. Sideband broadening up to 3 THz by 16.25 GHz modulation was achieved in the experiment with an Ar laser. Effective coherence time and length of the modulated light are 0.3 ps and 0.1 mm, respectively. This has applications in inertial confinement fusion.
