| Abstract: | The phase noises of a 10-m polarization-maintaining(PM) fiber and a 10-W PM fiber amplifier are experimentally measured.The results indicate that the 10-m PM fiber with similar phase noise could be used to investigate the architecture of master oscillator power amplifier coherent combination.A seven-element hexagonal fiber coherent array is developed to investigate the far-field distribution and phase controlling technique of a coherently combining fiber laser array.A hexagonal prism is designed as the comb... |
