File:Laser DSC09088.JPG

Description Helium-Neon laser demonstration at the Kastler-Brossel Laboratory at Paris VI: Pierre et Marie Curie. The glowing ray in the middle is a discharge tube (akin to that of a neon light), it is not the laser beam. The laser beam crosses the air and marks a red point on the screen to the right.

SOS Childrens Villages aims to make Wikipedia suitable for young learners. SOS Children believes education is an important part of a child's life. That's why we ensure they receive nursery care as well as high-quality primary and secondary education. When they leave school, we support the children in our care as they progress to vocational training or higher education. Help another child by taking out a sponsorship.
