Experimental observation of laser-stimulated radiative recombination

Spontaneous radiative recombination between protons and electrons to form hydrogen atoms with n in the range of 8 to 19 has been measured. CO2 laser light has been shown to induce stimulated radiative recombination to the n = 11 and 12 levels with an inferred gain in the cross-section of 1720 + or -...

Description
Summary:Spontaneous radiative recombination between protons and electrons to form hydrogen atoms with n in the range of 8 to 19 has been measured. CO2 laser light has been shown to induce stimulated radiative recombination to the n = 11 and 12 levels with an inferred gain in the cross-section of 1720 + or - 860 and 4790 + or - 2830 for a laser power of 12.6 and 15.3 W, respectively. This is in line with that predicted theoretically. (Author)
