The Vallée, Bernier, Olivier and Lord team’s first ultra-fast “fiber laser” in the visible range is among the scientific breakthroughs of 2023!

Retour aux nouvelles

The year 2023 ended on a positive note for the team of Marie-Pier Lord, Réal Vallée, Martin Bernier and Michel Olivier from COPL – ULaval, with a place in the Journal Le Soleil’s list of scientific breakthroughs for 2023. In fact, the development of the first fiber laser capable of producing femtosecond pulses in the visible spectrum, the results of which were published in Optics Letters last summer, has just been named one of the year’s scientific breakthroughs.

Congratulations to the whole team!
