International Day of Light 14.5.2022, Laser Centres HiLASE and ELI Beamlines

The HiLASE laser centre (Institute of Physics) is once again preparing a programme to celebrate the International Day of Light, this year exceptionally on Saturday 14 May, 2 PM – 7 PM.

During the International Day of Light, together with UNESCO, we commemorate the moment when Theodore Maiman introduced the first laser to the world on 16 May 1960. Since then, this scientific invention has contributed to improving the lives of many people. At the HiLASE Centre, we also strive to bring practical laser solutions to the real world, which is why this year we are once again taking part in the celebration of this important day.

In cooperation with another laser centre of the Institute of Physics of the CAS, ELI Beamlines, we are preparing lectures, short excursions and activities not only for children. We will keep you updated with details on this website or on Facebook.
