Abstract:

The principle of operation of systems that allow the construction of laser sources of pulsed radiation, in which a multifold increase in the peak output power of the radiation is achieved without increasing the energy of the power sources, is described, and the corresponding block diagrams are presented. The efficiency of devices with coherent synchronous combining using a single-frequency helium–neon laser emitting at 632.8 nm and an erbium laser emitting at 1550 nm in their composition is analyzed. Graphs showing the efficiency of systems with helium–neon and erbium lasers versus the number of fiber-optic delay lines are plotted. It is shown that the highest efficiency in the devices considered here can be achieved using radiation at a wavelength of 1550 nm.
