    摘要: A technique is described for eliminating feedback light in a high-power optical device. An optical device (54) is provided that generates, along an optical pathway, an output light (68) at a desired signal wavelength, wherein the generation of the output light at the signal wavelength results in the generation of a feedback light (74) at an undesired feedback wavelength. A port (76) is provided at a selected location along the optical fiber pathway. The port is terminated with a length of a filter fiber (78), wherein the filter fiber has loss characteristics at the feedback wavelength that result in the elimination of feedback light from the optical fiber pathway through the port.

    摘要: Modular set is formed by optical module (1) interconnected with control module (2) of electronic system. Optical module (1) is formed by at least two pairs (10, 11, 12, 13) of laser diodes connected in series and including Peltier cooler and thermistor, which are connected to inputs of polarizing fiber combiners (14, 15, 16, 17), and depolarized outputs of these polarizing fiber combiners are connected to inputs of a wavelengths combiner (18). Module (2) of the electronic system is formed by a control microprocessor (20) interconnected with direct current power supply source (21), with PID regulators (25) of laser diodes temperature, a display indicating temperature of individual laser diodes and current flowing through them, and a control panel. To the microprocessor (20) of the module (2) of the electronic system is connected a gate array (22) and to this gate array (22) are connected generators (23) of current impulses, which do not overlap in time, and their widths, repetition frequencies and amplitudes are adjustable, while the number of generators (23) of current impulses equals to the number of pairs (10-13) of laser diodes and their outputs are connected via power stages (24) to pairs (10-13) of laser diodes connected in series, and where to the power stages (24) is connected an analogue/digital converter (210), which is connected also to the microprocessor (20).
