Abstract

An evolutionary learning algorithm in conjunction with an ultrafast optical pulse shaper was used to control vibrational motion in molecular gases at room temperature and high pressures. We demonstrate mode suppression and enhancement in sulfur hexafluoride and mode selective excitation in carbon dioxide. Analysis of optimized pulses discovered by the algorithm has allowed for an understanding of the control mechanism.

      In the past decade, CARS microscopy has developed as a promising technique for imaging of various objects of biological interest, for example, living cells, cancerous cells, and also for combustion diagnostics, and monitoring of molecules. The recent advances in shaping of ultrafast femtosecond laser pulses25 along with demonstration of different experimental and theoretical techniques26–35,1,36,37 of driving a system to the desired quantum yield have made CARS a major tool of investigation of biological structures. Experimental configurations such as Box-CARS,38 FM-CARS,39 EPI-CARS,40 heterodyne CARS,41 polarization CARS,42 FT-CARS,43 and interferometric CARS44 are among the most promising ones.
