| 摘要 |
<p>The deflection unit 1 according to the invention is characterised essentially in that it comprises, means 6, such as a deflector of the "acousto-optic" type, for deflecting a low-power incident laser beam 2, and means 7 for making the deflected low-power incident beam 9 interact, in a Brillouin scattering nonlinear medium 11 like a gas such as methane (CH4), xenon or sulphur hexafluoride (SF6), or a liquid such as carbon disulphide (CS2) or acetone, with a high-power pump laser beam 10 forming, with the deflected beam 9, a non-zero angle " theta ".
<??>Application, in particular, to telemetry and to the guiding of weapons for which the laser beam used as reference must be able to undergo rapid changes of orientation within a sizeable angular field.
