Gnatenko, K.A.Vasko // International Young Scientists Forum on Applied Physics, Dnipropetrovsk, 30 september 2015. - С.1-4.http://openarchive.nure.ua/handle/document/8595In this paper, we present the configuration of erbium-doped fiber laser. The laser operates in passive mode locking. Usually in existing schemes fiber ring laser using mechanical adjustment mode locking by rotating in the space of the wave plates. In our optical system, we propose to use voltagecontrolled liquid crystal cells, to replace conventional polarization controllers (quarter-half-wave plate) inside the laser cavity. Using this innovation, freed from the mechanical adjustment mode locking, we plan to obtain the pulse width of the order of hundreds femseconds and an average power output of the order of tens milliwatts.enfiber laserfemsecondliquid crystalpolarizationwave plateAbstract of Thesis
