Nonlinear optics with broad-band lasers: Progress report for period July 15, 1986-July 1987
During this reporting period a number of significant results were obtained and new investigations were established. The studies of the fluctuation dynamics of pulsed dye lasers and of stimulated Raman scattering (SRS) were completed. The main results obtained in this work are: (a) mode intensities and phases were found to be correlated in a pulsed dye laser; (b) conditions were found under which the dye laser produced FM-locked output; (c) a method was found for smoothing the temporal shape of the dye laser pulses; (d) Stokes intensity autocorrelation and laser-Stokes cross-correlation measurements showed that the development of correlations between the pump laser light and Stokes light generated by SRS depends on the relationship between two time scales - that of the laser fluctuations and that of the molecular Raman response. A new multifaceted program has been established to study the statistical aspects of broadband continuous-wave dye lasers that are relevant to better understanding intracavity laser spectroscopy (ILS). The central, still unanswered, question in this field is: what mechanisms limit the mode lifetimes and thereby limit the present and ultimately achievable sensitivity of ILS. Our goal is to eliminate all extrinsic mechanisms, leaving only those intrinsic to the laser-quantum noise and deterministic chaos. 12 refs., 10 figs.
