Three-dimensional imaging using a femtosecond amplifying optical Kerr gate

摘要

An optical Kerr gate with the capability of light amplification and a femtosecond opening time in a special fast setup is applied to time-resolved imaging. Transient-induced anisotropy created by a first pump pulse is canceled by the perpendicular-induced anisotropy created by a delayed pump. The transverse resolution of the image is better than 70μm without degradation due to the optical Kerr effect or optical am- plification.
