20.500.12556/RUL-113739 Pulses on demand in fibre and hybrid lasers Pulzi na zahtevo v vlakenskih in hibridnih laserjih This paper presents an investigation of pulse-on-demand operation in fibre and hybrid lasers. Two methods for efficient gain control that enable the generation of laser pulses at arbitrary times with controlled pulse parameters are presented. The method of direct modulation of the pump power in the high-power laser oscillator is shown to generate pulses with a duration in the nanosecond range, with repetition rates varying during operation from a single shot to over 1 MHz. An advanced method using a combination of marker and idler seeding a fibre amplifier chain is investigated. Such a system can easily achieve repetition rates of several tens of MHz. The lasersʼ performances were successfully tested in a real environment on an industrial platform for laser transfer printing. Similar concepts were used for a laser source with ultrashort laser pulses (femtosecond range) on demand by using a mode-locked seed as a source and a solid-state amplifier to achieve high pulse energy and peak power. pulse on demand fibre lasers gain control arbitrary repetition rate pulzi na zahtevo vlakenski laserji nadzor ojačenja poljubna ponavljalna frekvenca true false true Angleški jezik Slovenski jezik Članek v reviji 2020-01-30 08:13:23 2020-01-30 08:13:26 2022-08-26 03:47:16 0000-00-00 00:00:00 2019 0 0 Str. 680-689 no. 11/12 Vol. 65 Nov./Dec. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535(045) 0039-2480 10.5545/sv-jme.2019.6352 16944411 762116 RAZ_Petkovsek_Rok_2019.pdf RAZ_Petkovsek_Rok_2019.pdf 1 E584A5DC46CBF5EB3E70B9B2CF59889A 28f44da492d3f5702190c0f6d32aceeca4e2444b6257ff416aa456df330dadd1 2628ef0a-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125842 https://www.sv-jme.eu/sl/article/pulses-on-demand-in-fiber-and-hybrid-lasers/ 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125841 Fakulteta za strojništvo 0 0 0
