Ruby lasers have chromium atoms doped in an aluminum oxide crystal. The energy level diagram for chromium in a ruby is shown in the figure above.   (a)Calculate the energy of photons that can pump chromium atoms in a ruby laser from the ground state to its second excited state. eV   (b)Calculate the energy of photons that can pump chromium atoms in a ruby laser from the ground state to its third excited state. eV   (c)Calculate the wavelength emitted by the ruby laser (in nm).  nm
a) The element helium is named for the Sun because that is where it was first observed. What is the shortest wavelength that one would expect to observe from a singly ionized helium atom in the atmosphere of the Sun? b) Suppose light with a wavelength of 388.9 nm is observed from singly ionized helium. What are the initial and final values of the quantum number nn corresponding to this wavelength? Enter your answers numerically separated by a comma
Your answer is partially correct. A laser emits light at wavelength A = 598 nm in a beam of diameter 3.7 mm and at an energy-emission rate of 5.5 mW. A detector in the beam's path absorbs the beam. At what rate per unit area does the detector absorb photons? Number 1.429048888 Units photons/s-m^2
