Abstract

A large, dc-electric-field-induced nonlinear optical susceptibility is exploited to produce ultraviolet radiation in the range 2453–2476 Å by the process of sum-frequency generation in sodium. The interaction is resonantly enhanced at the first intermediate level by the 3 ²P_3/2 state and at the second intermediate level by a Rydberg state. Conversion efficiencies of 10⁻⁵ have been obtained; improvement of this value by a factor of 10³ should be possible.
