Laser Radiation of Tissue Cultures

Abstract

The laser head, attached to a microscope is a significant advance in instrumentation for cytology and cytogenetics. The laser beam may be focused by the optics so that the beam size can be reduced to a diameter as fine as one micron. This has been done by Bessis. The laser beam may also impact microscopic preparations including tissue cultures through an arrangement outside of the microscope with the laser beam reflected into the microscope, yet the laser attacted to a microscope makes for greater technical control of laser microscopy. However, laser beams of other types of lasers such as Q-switching, second harmonics, gas lasers of various types, etc. may be directed from an external source through the microscope system. This flexible arrangement increases the range of laser microscopy.
