The Mode-locked Fiber Laser Of The Repetition Frequency Pseudo-randomed

With the development of laser technology in the modern battlefield, laser technology and laser fight against the development of anti-technology interaction and compete. The traditional laser pointer coding technology can not meet the development needs of modern technology, the need for more complex laser coding technology. Therefore, a more complex study of the extent of the ability to compete with the repetition frequency of the pseudo-random lasers, laser-guided technology for the development of a certain significance. Fiber mode-locked laser can generate ultrashort pulses of high repetition rate, it is today a new laser has the advantages of high-power, high conversion rate, high reliability and high flexibility, showing the incomparable advantage of other lasers It has important applications in the future battlefield.The main content of this paper is to design a pseudo-random variations repetition frequency mode-locked fiber laser, which can output high repetition rate ultrashort pulse repetition frequency may be changed according to the frequency of the injected signal, the pulse width can be as narrow as picosecond magnitude, the laser repetition rate of up to512times the maximum output harmonic realized between2.297MHz to1.176GHz adjustability demonstrates the repetition frequency of the feasibility of a pseudo-random.Innovation of this paper is the first use of fiber laser with a pulse repetition frequency of the pseudo-random changes, namely a pseudo-random repetition rate mode-locked fiber laser of this nature can be applied to laser-guided weapons in laser pointer, you can break the traditional encodings periodic strong disadvantage. And because the output pulses with a high repetition rate, can be effective against high frequency laser interference.
