Pulsed Fiber Laser

Compared with continuous laser, pulsed fiber laser has the advantages of high peak power, which is widely used in device processing, military defense and other areas. As the repetition frequency of pulsed fiber laser is low and therefore it cannot realize high rate transmission, this paper does the research on L-PPM modulation of pulsed fiber laser to find a method of effectively improving the modulation rate of pulsed fiber laser. Experimental results show that the L-PPM modulation can improve the transmission rate of the pulsed fiber laser whose repetition frequency is 200K to 1.387Mbps. The research results are useful for the application of pulsed fiber laser in communication.
