摘要

There is a necessity of development a stable and calibrated laser sources for modern WDM telecommunication systems. Additionally simultaneous oscillations of many wavelength are required for testing and diagnostic of such systems. This regime of operation is possible in Frequency Shifted Feedback Lasers (FSFL). The multiwavelength erbium doped fiber laser is presented in this paper. The acoustooptical Bragg frequency shifter (AOFS) in the laser cavity ensures stable and multi-frequency operation by preventing steady-state regime. The wavelengths forced by Fabry-Perot filter cover part of third window (1550 nm).
