Article

Results of experimental studies of the influence of the optical fiber (OF) temperatures on the pulse duration are presented. Optical radiation was input at different angles relative to the OF axis. It is revealed that low OF temperature (from –10 to –50°C) results in significant pulse broadening due to a change in the physical-mechanical properties of the protective OF coating. It is experimentally demonstrated that the residual change in the pulse duration (up to 0.3 ns) is preserved when returning from the negative temperatures (0 and –50°C) to room temperature. The pulse duration also increases with the optical radiation input angle.
