RefleKron Oy
 RefleKron Oy RefleKron Oy specializes in customized semiconductor saturable absorber mirrors (SESAMs) for ultrafast laser systems, focusing on mode-locking and Q-switching applications across a wavelength range from approximately 0.6 µm to 3.5 µm. The private company is based in Tampere, Finland. The Finnish company utilizes molecular beam epitaxy with materials such as GaAs, InP, and GaSb to tailor SESAM properties, including nonlinear absorption, saturation fluence, and relaxation time, for optimized laser performance and repeatability in industrial volume production. RefleKron supports a full product qualification cycle to ensure stable supply for large-scale manufacturing and offers consulting services for customized SESAM solutions. The company also engineers absorber defect density to control absorption recovery dynamics, enabling adjustable relaxation times from sub-picoseconds to nanoseconds. | Directeur/Bestuurslid | 01-01-2018 |
