Conjugated molecules, with large optical nonlinearities, are tested as materials usable for femtosecond optical Kerr shutter technique. With β‐carotene, in acetone solution, we have achieved responses limited by the 100‐fs width of the optical pulses and characterized by a resolution better than 1 ps with a dynamic range of 100.
