| titleOfInvention | OPTICAL BEAM ORIENTATION DEVICE. |
| abstract | In the optical beam orientation device described (10) are incorporated a laser (12), three Brillouin phase shifters (22 to 26, 44 to 48, 54 to 58), a four-wave mixing cell (FWM) (40 ), as well as a low power beam rudder (62). The first phase shifter (22 to 26) and the mixing cell (40) contain TiCl4 and the other phase shifters (44 to 48, 54 to 58) contain 20% CCl4 / 80% CS2. The first and third phase shifters (22 to 26, 54 to 58) cause a downward movement of the frequency of the laser beam (16) which is equal to deltanuA and deltanuB, respectively. The light (16 ') from the first phase shifter (22 to 26) is amplified and provides an input for the first pumping beam in the mixing cell (40). This light then passes through the second phase shifter (44 to 48), in order to cause a downward frequency shift equal to deltanuB, and then returns in the form of a second cell pumping beam (16 ''). The light (18 ') from the third phase shifter (54 to 58) passes through the low power beam rudder (62) into the cell (40), in the form of a beam with a weak input signal (18' '). The cell (40) reacts to the pumping beams (16 ', 16' ') and to the signal beam (18' ') by generating a high power beam (68), which constitutes a phase conjugate of the signal beam (18' ' ) and retraces part of its oriented trajectory. |
