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 4s6d1D2-4snf1Fº3 spectrum for n = 11–16 is observed. Two other series of lines are identified as 4s5f1Fº3-4sng1G4 and X-4sng1G4 transitions.
