Study on high-average-power pulsed fiber laser
Abstract
In 1961, as the first laser was invented, the laser technology is developed rapidly. Types of lasers can be divided into different substances by the operations material, such as solid-state lasers, gas lasers and chemical laser. Fiber laser as a new type of solid-state lasers, comparing with traditional solid lasers, fiber laser has distinguished superiority in efficiency, volume, beam quality, compactness and so on. Especially, the pulsed fiber laser is very important for the present and potential application including medical treatments, scientific researches, military affairs, material processing and so on. At present, up to ten thousand watts of output power in continuous-wave (CW) mode has been demonstrated in a single transverse mode. Dawson et al. made a study on the output power of fiber lasers, which showed the maximum output power of fiber lasers, which showed the maximum output power of fiber lasers with the diffraction limit of for wide bandwidth and for narrow bandwidth, pulse fiber laser can achieve a higher peak power laser output, to make up for the many limitations of the CW fiber laser such as the laser and the target for interaction, or nonlinear frequency conversion applications, it is an important research direction in the field of high power fiber laser technology. In this dissertation, we have done some theoretical and experimental study on high-power narrow linewidth pulsed fiber lasers and fiber laser frequency doubling technology.
The first chapter is a brief introduces of Yb3 +-doped double-clad fiber firstly. We
analyze the three main methods which are getting the pulse fiber laser: the master-oscillator power amplifier (MOPA), Q-switched and mode-locked techniques, and give some typical research results of the research institutes at home or abroad. Moreover introduce the latest progress of the nonlinear harmonic generation of fiber laser technology
