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 1D2-4snf 1F° spectrum for n = 11-16 is observed. Two other series of lines are identified as 4s5f 1F3°-4sng 1G4 and X-4sng 1G4 transitions. © 1981 Optical Society of America.
