Abstract

PURPOSE:To modulate second harmonic wave intensity at a high speed by projecting laser light to an org. nonlinear optical element having a Pockels effect to generate the second harmonic waves and applying an electric field thereto to change the refractive index, thereby modulating the intensity of the second harmonic waves. CONSTITUTION:The laser light is projected to the org. nonlinear optical element 1 which generates the second harmonic waves by the light of a laser light source and has the Pockels effect to generate the second harmonic waves. The electric field is impressed by a power supply 2 to the medium 1 to change the refractive index by the Pockels effect. The intensity of the second harmonic waves is modulated in such a manner. The intensity modulation of the second harmonic waves is thus executed and in addition, the modulation at the extremely high speed is possible.
