Abstract

Two types of parametric four-wave mixing are observed when a single intense laser beam propagates through Na vapor near the D1 and D2 resonance lines. The first is related to three-photon scattering, while the second results from the coherent parametric interaction of the laser with excited-state Raman scattering. Identification of the two processes was greatly facilitated by the use of an optical multichannel detector system to observe the total emission spectrum for each individual laser pulse. The experimental conditions that determine whether stimulated emission or one or both of the four-wave mixing processes dominates the emission spectrum are described.

Schematic representation of the Na-laser interaction showing the two types of FWM. (a) Three-photon-type FWM. (b) Raman-type FWM. The straight arrows represent the incident laser radiation, while the parametrically generated frequencies are shown as wavy lines.

Fig. 2

Single-shot spectra obtained for ωL tuned to the high-frequency side of D1 (δ = 2.95 cm−1). (a) Spectra taken at a Na density of ~ 1014 cm−3 and a laser intensity of ~2 × 106 W/cm2 and showing TPS-type FWM. (b) The spectrum at a Na density n ~ 1015cm−3 with a laser intensity ~2 × 106 W/cm2 (solid line) and ~2 × 105 W/cm2 (dashed line).

Fig. 3
Fig. 3

Single-shot spectrum showing the Raman-type FWM. The dashed lines are the spectrum observed in the backward direction. The detuning of the laser is to the low-frequency side of D2(δ = 15.3 cm−1), with a laser intensity of ~5 × 106 W/cm2 and a Na density of ~1015/cm3. The intensity ratio between the forward and the backward emission is arbitrary. The spectrum is incomplete because of the limited detector size, and a peak at ~16 940 cm−1, corresponding to S2, is not shown.
