Atomic Rydberg-state spectroscopy of Ca I using pulsed colorcenter lasers.
The utility of using color-center lasers for atomic spectroscopy is demonstrated. Pulsed, color-center lasers are used in conjunction with pulsed dye lasers for multiphoton ionization spectroscopy studies of Ca I. The 4s6d(1)D(2)-4snf(1)F( masculine)(3) spectrum for n = 11-16 is observed. Two other series of lines are identified as 4s5f(1)F( masculine)(3)-4sng(1)G(4) and X-4sng(1)G(4) transitions.
