Abstract

The invention discloses an optical pulse sequence repetition frequency multiplication control device and method. The device comprises: a pulse laser source used for generating an initial optical pulse sequence with a preset repetition frequency and a preset pulse width; an amplitude modulation module connected with the pulse laser source and used for modulating the amplitude of the initial optical pulse sequence to obtain an intermediate optical pulse sequence; and a dispersive medium, wherein the dispersive medium provides a dispersion value to meet a time domain Talbot effect condition, is connected with the amplitude modulation module, and is used for converting the intermediate optical pulse sequence into a repetition frequency multiplication target optical pulse sequence and outputting the target optical pulse sequence so as to realize flexible adjustment of repetition frequency multiplication times.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to an optical pulse sequence repetition frequency multiplication control device and method. Background technique [0002] Optical pulse sequences are widely used in high-speed optical communication systems, optical signal processing, spectroscopy and other important fields. At present, there are various devices and methods to control the repetition frequency of the optical pulse sequence to realize the generation of high-speed optical pulse sequence. Mode-locked lasers are the most common pulsed laser sources, but due to the limitation of the internal cavity structure, the adjustment range of the repetition frequency of the output optical pulse train is very limited. Commercial optical bit rate multipliers are often used to multiply the repetition frequency of high-speed optical pulse sequences, but the multiplication factor is relatively fixed and the adjustment lacks flexibility, ...
