Abstract

In this paper are given results of investigations of characteristics of radiation of the compact fiber laser. It is established that at work in pulse and in pulse periodic modes the fiber laser generates enough stably radiation with length of a wave 1,083 microns with peak power to 1,5 ÷ 2 kW. The area of stable generation of radiation is limited to a pumping current 8A. There are shown possibilities of treatment of materials by radiation of the investigated laser.
