Continuously Tunable Sum-Frequency Generation Involving Sodium Rydberg States

Published

Journal Article

Broadly tunable sum-frequency generation has been observed in a vapor of atomic sodium in the presence of a dc electric field. This field induces a x(2) nonlinearity which is resonantly enhanced when the sum frequency corresponds to the energy separation between the ground state and an atomic Rydberg state. In a vapor of number density 4 X 1014 cm-3, we obtain an energy conversion efficiency as large as 3 X 10–4 and a x(2) as large as 1.2 X 10–8 ESU. We have also observed sum-frequency generation in the absence of an applied dc field, and we relate these observations to mechanisms that have been proposed to explain this effect. © 1984 IEEE
