a: Building a laser ~
b: A long climb


"Challenge. It probably goes without saying that the production of coherent light - even if for a short time - from a totally homemade laser represents a tremendous achievement with enormous satisfaction value. Why do people climb mountains? Building a laser is like climbing from the depths of the Pacific to the top of Everest and beyond. Note: If you don't believe this then you will probably not have enough motivation to complete the project!"
