This booklet is a evaluation of previous and present experiences and destiny plans of the Laser Laboratory in Cincinnati and a few of the contributions of laser study teams in different scientific facilities. particular thank you are as a result Directing Physicist of the Laser Labora tory, R. James Rockwell. with out his suggestion, consistent supervision and corrections, this enthusiastic investigator may proceed to dissatisfied even many extra humans than he has performed already. The excuse, after all, is to stimulate a lot wanted curiosity and regulated examine and improvement of the laser for biology and drugs. The affiliate study Physicist, Ralph Schooley, has labored with many stages of laser learn yet particularly in Q spoiling, Raman spectroscopy, and the just about alchemy of holography. Holography, as of now, offers many possibilities for Gumperson's legislations, "If something can get it wrong, it's going to. " honest appreciation is expressed to the Surgeons within the Laser Labora tory, who've provided medical and investigative surgical supervision usually lower than nice problems, Dr. V. E. Siler and Dr. Bruce Henderson. we're thankful for support from the Directing Biologist of the Laser Labo ratory, Edmond Ritter, the Director of Laser Neurosurgery, Dr. Thomas Brown and the Professor of Neurosurgery, Dr. Robert McLaurin, for vital and easy paintings in laser neurosurgery. targeted thank you are given to Robert Meyer, who has given many of the remedies in cautious and skillful style, and his affiliate, Robert Otten.

As indicated, laser beams of different colors can be combined to form a single beam. Holography concerns lasers, and so area and personnel safety programs must be included here also. This is especially true during the making of the holograms. If holograms can be viewed in white light and not be the coherent laser, then laser protective glasses are not needed. As yet, the special safety requirement for all phases of laser holography have not been worked out. Van Lighten, Grolman, and Lawton have proposed a holographic fundus camera for research in ophthalmologic holography.
This may be accomplished with plume traps and with the optical instruments currently available for the transmission of light and especially with the use of specially prepared curved tapered quartz rods. Continued research is necessary in the field of fiber optics to attempt to adopt this for laser transmission especially with the argon laser for biomedical applications. Studies on neodymium doped fibers are continuing. REFERENCES Bell Telephone Laboratories: Laser Knife. Cincinnati Enquirer, May 7, 1967.
Both phases are important in current laser research for studies of the target area and plume, and also for area and personnel protection in the laser laboratory. Conventional still and high-speed cine cameras, even as high as a million frames per second, have been used. For the study of the biomedical applications of the laser, pre-impact, impact and post-impact pictures are done, usually in color. For most of the industrial applications of the laser, such as in welding and drilling, black-and-white pictures are usually taken.
