Łukasz Kornaszewski received his PhD in femtosecond nonlinear optics at Heriot-Watt University in Edinburgh, UK. After that he spent a year as a project engineer in the Optical Parametric Oscillator group in ICFO, Spain. Then he moved back to Scotland to join M Squared Lasers as a laser design engineer where he stayed for over 8 years. Recently he returned to Poland and became a member of PoB lab serving as a link between the group and industry, namely Warsaw-based manufacturer of femtosecond fibre lasers, Fluence.
His MSc at University of Warsaw in the Ultrafast Phenomena Lab of prof. Radzewicz was focused on highly efficient broadband second harmonic generation of femtosecond laser pulses using angular phase matching.
During his PhD studies in the Ultrafast Laser Group of prof. Derryck Reid at Heriot-Watt University he made three experiments. First one was building a femtosecond Ti:sapphire-pumped OPO and applying it to FTIR methane sensing in a photonic bandgap fibre. Second one involved creating tailored-shape femtosecond pulses in second harmonic generation process in an aperiodically poled lithium niobate crystal. Third one resulted in a patent granted, describing a long-cavity OPO for micromachining applications which has been built in the lab.
In ICFO he took part in an EU MIRSURG project aiming at developing a mid-IR laser for brain surgery, as a member of prof. Majid Ebrahim-Zadeh's Optical Parametric Oscillator group. His role was to build a versatile autocorrelator for femto- and picosecond pulses in near- and mid-IR wavelength range and training students, including supervision of an MSc project.
In M Squared Lasers he developed an automated tunable femtosecond Ti:sapphire Sprite laser and organised its production.
His joining the Physical Optics and Biophotonics Group of prof. Wojtkowski in the Institute of Physical Chemistry of PAS in Warsaw has a long-term target of helping to close the gap and create fruitful links between academia and industry in the Polish laser community, especially in the field of medical diagnostics and treatment.
