Atomic Rydberg-state spectroscopy of Ca i using pulsed color-center lasers

Abstract
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 4s6d1D2–4snf1F3° spectrum for n = 11–16 is observed. Two other series of lines are identified as 4s5f1F3°–4sng1G4 and X–4sng1G4 transitions.
