摘要：

We describe the promising development of third-harmonic generation (THG) in laser scanning microscopy for study of the functional imaging of live biological cells. The dynamics of Ca2+ in biological cells is shown. The Ca2+ signal consists of a transient increase in the intracellular concentration. THG microscopy allows one to temporally visualize the release of Ca2+ from internal stores and (or) calcium influx. (C) 2001 Optical Society of America.
