"Infrared Transmitting Fibers and their Applications in Science, Industry, & Medicine"

Prof. Abraham Katzir
School of Physics and Astronomy, Tel Aviv University

This lecture will take place in Lev Auditorium

     Silica glass fibers are totally opaque in the mid-IR in the spectral range 3-30µm. Optical fibers were extruded in our lab from crystalline silver halides (e.g. AgClBr), which are highly transparent in the Mid-IR. These fibers make it possible to carry out novel measurements in remote locations and in real time. Some of these will be discussed:
 (1) Non contact thermometry. 
 (2) Fiberoptic thermal imaging. 
 (3) Fiberoptic spectroscopy and its applications: 
      A. Environmental protection and pollution monitoring. 
      B. Early diagnosis of diseases. 
      C. Phase transition measurements. 
 (4) Endoscopic laser surgery and therapy. 
 (5) Laser bonding of tissues. 
 (6) Fiberoptic interferometry for Mid-IR astronomy. 
 (7) Mid-IR fiber lasers. 
 (8) Near Field Scanning Mid-IR microscope. 

IR transmitting fibers will pave the way for totally new methods and applications in science, industry, environmental protection and medicine.
