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.

Background: Lithium di-silicate dental ceramics bonding, realized by using different resins, is strictly dependent on micro-mechanical retention and chemical adhesion. The aim of this in vitro study was to investigate the capability of a 1070 nm fiber laser for their surface treatment. Methods: Samples were irradiated by a pulsed fiber laser at 1070 nm with different parameters (Peak Power from 5 kW to 5 kW, RR 20 kHz, speed from 10 to 50 mm/s, total Energy Density from 1.3 to 27 kW/cm2) and the thermal elevation during the experiment was recorded by a Fiber Bragg Grating (FBG) temperature sensor. Subsequently, the surface modifications were analysed by optical microscope, Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). Results: With a Peak Power of 5 kW, RR of 20 kHz and speed of 50 mm/s, the microscopic observation of the irradiated surface showed increased roughness with small areas of melting and carbonization. EDS analysis revealed that, with these parameters, there are no evident differences between laser-processed samples and controls. Thermal elevation during laser irradiation ranged between 5 °C and 9 °C. Conclusions: 1070 nm fiber laser can be considered as a good device to increase the adhesion of Lithium di-silicate ceramics.
