How to Store Light – and to Understand the Laser Principle

We have now managed to find a way for storing light over long times – even though we constantly need to supply energy in order to compensate for the permanent losses. In this sense, it is like a not perfectly insulated storage tank for hot water, which you permanently need to heat in order to keep it hot.
