Fibre lasers - conditioning constructional and technological

Zając A., Dorosz D., Kochanowicz M., Skorczakowski M., Świderski J.

Bulletin of the Polish Academy of Sciences. Technical Sciences

2010

Vol. 58, nr 4

491-502

In this paper the actual level of fiber lasers’ development is presented. There is also presented the analysis of technological and constructional conditions that limit energy parameters of those sources. Authors also show a construction and a technological work, conducted in Poland, which led to improving energy and exploit parameters of fiber lasers.

Diode-seeded nanosecond Yb-doped fiber amplifier operating at the repetition rate up to 500 kHz

Świderski J., Zając A., Skorczakowski M.

Optica Applicata

2008

Vol. 38, nr 4

The paper presents a laser system developed in MOFPA (Master Oscillator Fiber Power Amplifier) configuration. A pulsed single-mode laser diode operating at the wavelength of 1060-nm was used as a seed. An ytterbium-doped double-clad Large Mode Area fiber pumped by the radiation of 978-nm played a role of an active medium. The developed laser system generated a pulse train with duration ranging from about 11 ns to 200 ns at the repetition rate up to 500 kHz, regulated independently of the system gain. The maximum amplification of the fiber amplifier was 32 dB.
