Abstract
A system and method for generating ultra-short pulses intended to be inserted into a ring laser with a regulator of a pulsed signal of a certain intensity, the system includes an optical attenuator that allows the intensity of the pulsed signal to be adjusted at the input of an optical guide section, and a distributed amplification device inserted in the optical guide 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.
Claims13
A laser having a laser cavity comprising:
- a regulator of a pulsed signal selected from a modulator or a saturable absorber and comprising a system for generating pulses having a peak power greater than 0.6 megawatts and a duration of less than 1 picosecond, located within the laser cavity and positioned after the regulator with respect to the direction of light propagation, the laser comprising:
- an adjustable optical attenuator;
- an optical guide through which the signal is transmitted and configured to increase the length of the laser cavity, the optical guide positioned after the optical attenuator with respect to the direction of light propagation;
- and
- a distributed amplification device based on the Raman effect, located within the optical guide and configured to regulate intensity of the signal that propagates through the optical guide;
- wherein the optical attenuator is configured to adjust the intensity of the pulsed signal prior to entry into the optical guide such that it coincides with that required for the pulsed signal to enter the optical guide as a signal that generates solitons.
