Femtosecond laser micromachining in the conjugated polymer MEH–PPV
Source abstract
Abstract
Femtosecond-laser micromachining of poly[2-methoxy-5-(20-ethylhexyloxy)-p-phenylene vinylene] films is investigated using 130 fs pulses at 800 nm from a laser oscillator operating at 76 MHz repetition rate.We investigate the effect of pulse energy and translation speed on the depth and morphology of the micromachined regions.We quantified the MEH-PPV photobleaching induced by the fs-laser, and the conditions in which the emission of MEH-PPV is preserved after the micromaching.
