Intracavity polarization control in mode-locked Er-doped fibre lasers using liquid crystals

Nikodem M., Krzempek K., Zygadlo K., Dudzik G., Waz A., Abramski K., Komorowska K.

Opto-Electronics Review

2014

Vol. 22, No. 2

113-117

In this paper we present a novel configuration of an NPR mode-locked Er-doped laser. This new optical setup uses voltage controlled LC cells to replace standard retarders (quarter- and half-waveplates) inside the laser cavity. Using this novel, mechanical-adjustment-free setup a mode-locking was obtained with sub-500 fs pulse duration and an average power exceeding 40 mW. Presented results show that using simple LC cells, an optical layout of an NPR mode-locked laser can be greatly simplified.

Mode locked erbium doped fiber ring laser

Lamperski J.

Poznan University of Technology Academic Journals. Electrical Engineering

2007

No 54

109-116

In the paper, results of the research on properties of a basic configuration of an erbium doped mode locked fiber ring laser were presented. Fine modal structure of the fiber ring laser was investigated. Results of time and optical frequency domain measurements of mode-locked erbium ring lasers were shown.
