用于在激光器中生成高功率超短脉冲的系统和方法

Abstract

[ZH] 本发明涉及用于生成超短脉冲的系统(1)和方法，所述系统(1)旨在插入具有特定强度脉冲信号的调节器(7)的环形激光器(10)中。所述系统(1)包括光学衰减器(2)和分布式放大装置，所述光学衰减器(2)允许在所述光学引导部段(3)的输入处对所述脉冲信号的强度进行调整，所述分布式放大装置插入所述光学引导件(3)中以使在其中管理所述信号的功率成为可能，由此使得所述信号作为孤子或自相似脉冲传播而没有不必要的失真，即使所述激光器腔室的长度增加，从而增加了所述脉冲信号的功率并使得超越此类激光器(10)的常规功率限值成为可能。

[EN] The invention relates to a system (1) and method for generating ultra-short pulses intended to be inserted into a ring laser (10) with a regulator (7) of a pulsed signal of a certain intensity. The system (1) comprises an optical attenuator (2) that allows the intensity of the pulsed signal to be adjusted at the input of an optical guide section (3), and a distributed amplification device inserted in the optical guide (3) that make it possible to manage the power of the signal therein, so that it propagates as solitons or as self-similar pulses without suffering unwanted distortions despite the increase in the length of the laser cavity, increasing the power of the pulsed signal and making it possible to exceed the usual power limits of this type of laser (10).
