Laser Applications in Biological Sciences

Abstract

Various applications of lasers in the field of biological sciences are reviewed briefly. It is shown that remarkable features of laser beams, such as high degree of coherence, high monochomaticity and directionality, good focusability, high intensity and high electric field at the focused sopt, ultrashort pulse duration and so on, are utilized to the fullest in these applications. Examples to employ lasers in Raman and fluorescence spectroscopy, ultrafast spectroscopy, light scattering, laser microscopy, selective excitation, flow cytometry, microsergery, etc. are presented.
