Most system analyses of CW high-power lasers propagating in the atmosphere assume a simple additive linear relation of the impact of thermal blooming and optical turbulence in the atmosphere to the propagated laser beam spreading. In other words, bot

We have developed a fiber laser system capable of producing over 100W of average power. We have achieved 1.5mJ/pulse/fiber resulting in peak powers in excess of 2MW with 0.6ns pulses and near diffraction limited beams. In another fiber, we have achie

A new type of stress location sensor is discussed, in which the frequency-modulated continuous wave (FMCW) technique is used to detect the difference in propagation time between two optical paths in an optical fibre interferometer. The interferometer
