20.500.12556/RUL-138101 Pulse-on-demand laser operation from nanosecond to femtosecond pulses and its application for high-speed processing In this manuscript we present a true pulse-on-demand laser design concept using two different approaches. First, we present a fiber master oscillator power amplifier (MOPA) based quasi-continuous wave (CW) laser, working at high modulation bandwidths, for generation of nanosecond pulses. Second, we present a hybrid chirped pulse amplification (CPA)-based laser, combining a chirped-pulse fiber amplifier and an additional solid-state amplifier, for generation of femtosecond pulses. The pulse-on-demand operation is achieved without an external optical modulator/shutter at high-average powers and flexible repetition rates up to 40 MHz, using two variants of the approach for near-constant gain in the amplifier chain. The idler and marker seed sources are combined in the amplifier stages and separated at the out using either wavelength-based separation or second harmonic generation (SHG)-generation-based separation. The nanosecond laser source is further applied to high throughput processing of thin film materials. The laser is combined with a resonant scanner, using the intrinsic pulse-on-demand operation to compensate the scanner%s sinusoidal movement. We applied the setup to processing of indium tin oxide (ITO) and metallic films on flexible substrates. arbitrary repetition rate fiber lasers gain control high speed processing pulse-on-demand poljubna ponavljalna frekvenca vlakenski laserji kontrola ojačenja hitro procesiranje blisk na zahtevo true false true Angleški jezik Slovenski jezik Članek v reviji 2022-07-11 07:53:04 2022-07-11 07:53:14 2022-09-15 04:16:17 0000-00-00 00:00:00 2021 0 0 10 str. iss. 4/5 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-07-14 621.7.015:621.375.826 2192-8576 10.1515/aot-2021-0020 74192131 Petelin_..._Pulse-on-demand_laser_operation_from.pdf Petelin_..._Pulse-on-demand_laser_operation_from.pdf 1 903EDD9D23F9860906BB2A413DFD9B5A 01fdc509f7a472414dae6c58523e9eb6e8f964fca5a4b1f14f353519b2f2379f 134beff3-00de-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158306 https://www.degruyter.com/document/doi/10.1515/aot-2021-0020/html 1 8739fe68-00dd-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158304 Fakulteta za strojništvo 0 0 0
