Abstract

Asymmetrically broadened line shapes observed in the stimulated Raman and elastically scattered spectra from a CS2 droplet are manifestations of phase modulation by means of the intensity-dependent index of refraction. Unique features of the droplet morphology in enhancing the internal fields at the input and Stokes wavelengths and in prolonging the decay time of the waves within the droplet, which acts as an optical cavity, are discussed.

The SRS spectra (a) from a CS2 droplet (~35 μm in radius) collected at 90° and (b) from CS2 in an 11-cm optical cell collected in the forward direction. The same incident power was used for both (a) and (b). The CS2 ν1 stretching mode has a Raman shift of 658 cm−1, and each of the nth-order Stokes has a Raman shift of n × (658 cm−1). The intensity at the incident wavelength (INC) is diminished by-the throughput of the spectrograph and a long-pass color filter.

Fig. 2

When a high-dispersion spectrograph is used, the line shapes of the first Stokes SRS from CS2 in an 11-cm cell and from a CS2 droplet (~35 μm in radius) are resolved. The sharp peaks in the CS2 droplet emission are separated by nearly equal wave-number spacing and are associated with MDR’s.

Fig. 3

The normal elastic scattering spectrum from a CS2 droplet ~35 μm in radius is asymmetrically broadened on the longer-wavelength side of the incident radiation (INC) at 532 nm. The scattered intensity at 532 nm is greatly suppressed (by ~104×) by the triple spectrograph. The peak at ~535 nm is an artifact of the spectrograph bandpass and the monotonic decrease of the phase-modulation-broadened elastic scattering toward longer wavelength.

Comparison of the SRS line shape of the first Stokes wave (2932 cm−1) from (a) a pure-ethanol droplet and from (b) a droplet containing a 1:9 mixture of CS2 and ethanol. The additional peaks on the longer-wavelength side are associated with two sets of MDR’s within the CS2 phase-modulation-broadened ethanol Stokes emission.
