Who Invented Lasers?

Theodore Maiman is credited with inventing the first optical laser, known as the ‘ruby laser’ in 1960. Albert Einstein first came up with the idea, and several other men made similar inventions before 1960. Gordon Gould was one of these men. He was believed to have invented the first laser in 1958, but failed to file for a patent so others used his ideas.You can find more information here:
