Problem P. 3794. (April 2005)
P. 3794. In an experimental device where controlled nuclear fusion is generated, a solidstate laser emits infrared light in 1.1^{.}10^{11} s at the wavelength of 1060 nm with a power of 10^{14} W. For comparison: a school HeNe laser emits red light at the wavelength of 633 nm with a power of 10^{3} W. For how many days should the HeNe laser work to emit the same number of photons as the solidstate laser does in 1.1^{.}10^{11} s?
