Abstract
A coherent anti-Stokes Raman spectroscopic (CARS) imaging device especially adapted to observe specific molecular groups in living cells. Two laser beam pulses of different wavelengths in the visible or UV spectra and of picosecond duration are used to simultaneously illuminate a sample (e.g., a living cell) containing molecules of the type it is desired to observe. By proper selection of the laser frequencies, the molecules are excited to emit characteristic coherent anti-Stokes radiation which can be imaged through a microscope or other device.
