Abstract

The invention discloses a high-energy dissipative soliton resonance rectangular pulse generating system, which comprises: a 9-shaped resonant cavity based on a nonlinear amplifying annular mirror mode-locking technology, a double-clad thulium-doped optical fiber pre-amplifier, and a double-clad thulium-doped optical fiber main power amplifier, wherein the 9-shaped resonant cavity is connected to the pre-amplifier; the pre-amplifier is connected with the main power amplifier; the 9-shaped resonant cavity is configured to generate a dissipative soliton resonance rectangular pulse which is pre-amplified by the pre-amplifier and transmitted to the main power amplifier to be subjected to power amplification such that the high-energy dissipative soliton resonance rectangular pulse is obtained. The dissipative soliton resonance rectangular pulse can be obtained through the resonant cavity, and then is subjected to the power amplification by an optical fiber amplifier, thereby obtaining the high-energy dissipative soliton resonance rectangular pulse, and outputting a high-energy rectangular laser pulse with an adjustable pulse width.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a system for generating a dissipated soliton resonance rectangular pulse. Background technique [0002] Mode-locked pulsed fiber lasers have important application values ​​in research fields such as laser spectroscopy, medicine, lidar, material processing, and supercontinuum generation. Mode-locked pulsed fiber lasers can generate traditional negative dispersion solitons, stretched pulses, self-similar pulses, and dissipative solitons under different intracavity dispersion characteristics. Under the balanced effect of negative dispersion in the resonator and fiber nonlinear effect, the traditional negative dispersion soliton mode-locked pulse can be realized. Under the constraints of the soliton area theorem, the traditional negative dispersion soliton pulse energy is often limited to the order of 0.1nJ. Compared with traditional negative dispersion solitons, the energy of stret...
