Abstract

Resonance enhancement factors of 10 to 100 have been observed for the electronic Raman scattering transitions in crystals of pure ErPO4 and 1% Er3+ diluted in LuPO4. The resonances were excited by the 488.0-nm line of an argon-ion laser. This line is nearly coincident with the crystal-field levels of the 4F7/2 multiplet of Er3+. The differences in relative intensities between the transitions in ErPO4 and those in 1% Er3+ in LuPO4 arise from shifts in the energy levels in the two systems and suggest that quantum-mechanical interference effects play an important role.
