Abstract

The structural scheme and operation principle of a system with a synchronous incoherent combination of laser pulses in a ring delay line are presented. An analysis of the effectiveness of such systems is performed for the case of quartz or polymer optical fibers acting as ring delay lines, where radiation at wavelengths of 450, 532, 650, 850, 1310, or 1550 nm circulate. The dependences of the maximum coefficient of energy efficiency on the repetition rate of the initial laser pulses are obtained. The system is shown to achieve energy efficiency when the repetition rate of the initial pulses exceeds a certain cutoff frequency, which lies within the range from a single kilohertz to tens of meghertz.
