K. Puech et al., PICOSECOND DEGENERATE 4-WAVE-MIXING IN COLLOIDAL SOLUTIONS OF GOLD NANOPARTICLES AT HIGH REPETITION RATES, Optics letters, 20(15), 1995, pp. 1613-1615
Time-resolved degenerate four-wave mixing experiments on a colloidal s
olution of 50-nm gold particles in acetone, using a high-repetition-ra
te laser source, are presented. The signal is found to depend strongly
on the repetition rate of the incident radiation and above a frequenc
y of 300 kHz is impossible to measure. (C) 1995 Optical Society of Ame
