Highly adaptable gain-switched fiber laser with improved efficiencyAgrež, Vid (Avtor) Petkovšek, Rok (Avtor) fiber laserspulsed lasersytterbium fibersA highly adaptable fiber laser with pulse-on-demand and precision pulse-duration tuning is presented. It is based on a compact optical design combining the gain-switching technique with the all-fiber master oscillator and pump-recovery amplifier architecture. The approach of laser-pulse stability control by compensation pumping and pulse-duration control by changing the pump wavelength are introduced. In order to prove the concept, a laser setup capable of producing laser pulses with an average power of up to 30 W and a peak power of approximately 1 kW at an improved efficiency and an arbitrary repetition rate is presented.20192019-05-09 13:31:50Članek v reviji107643UDK: 535(045)ISSN pri članku: 1094-4087DOI: 10.1364/OE.27.012100COBISS_ID: 16599835OceCobissID: 8636438slV članku navedeno: "© 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement"; s povezavo https://www.osapublishing.org/library/license_v1.cfm (29. 3. 2021).
