Optical pumping of CII ions in a vacuum arc discharge using AlIII ions in a laser produced plasma is described. The CII, 2p-5d, 560.437 A transition was selectively pumped by line radiation from the AlIII, 3p-5s transition at 560.433 A. The wavelength mismatch is less than the Doppler width of the AlIII line. Four transitions in CII, from the 5d, 5f, 4s, and 2p/sup 2/ levels were studied simultaneously to examine the collisional-radiative redistribution of the pumped, 5d population. Electron density and temperature were measured in the C plasma. The Al plasma was characterized by measurements and numerical modeling in order to estimate the intensity of the AlIII pump line. A collisional-radiative model of the CII level populations was constructed with the measured density and temperature as inputs. Comparison of this model with the measurements allows discussion of the feasibility of building a UV laser with such a pumping scheme.
