ABSTRACT:
The optical phase modulator device comprises a source of short laser pulses, a material having self-induced variation in refraction index, and an interferometer device interposed between the source of short laser pulses and the material having self-induced variation of refractive index in order to form four fragmented waves for which the average value of the correlation product is zero. The device enables stable optical phase shifts of more than 2.pi. radians to be obtained in beams having a regular geometrical structure, and it is also applicable to high power laser amplification.
