Solved: Fusion is the process by which the sun produces
Chapter 30, Problem 30.94(choose chapter or problem)
Fusion is the process by which the sun produces energy. One experimental technique for creating controlled fusion utilizes a solidstate laser that emits a wavelength of 1060 nm and can produce a power of 1.0 1014 W for a pulse duration of 1.1 1011 s. In contrast, the helium/neon laser used in a bar-code scanner at the checkout counter emits a wavelength of 633 nm and produces a power of about 1.0 103 W. How long (in days) would the helium/neon laser have to operate to produce the same number of photons that the solid-state laser produces in 1.1 1011 s?
