<p>AN OPTICAL DEVICE FOR SUSTAINING A RADIANT ENERGY PULSE WHICH CIRCULATES WITHIN A MONOMODE WAVEGUIDE, A GYROMETER AND A HYDROPHONE EQUIPPED WITH SAID OPTICAL DEVICE An interaction medium in which a photoinduced phase grating has been permanently recorded beforehand is coupled to the two ends of a monomode waveguide. A first wave which is a pulse travels through said waveguide and interferes with a second pumping wave in order to permit energy transfer from the second pumping wave to the first wave.</p> |
