    Since the discovery of the laser in the 1960s, a great amount. of research activity has led to an impressive increase of the overall. performances of the sources emitting in the visible or in the infrared. spectral regions. The most significant achievements for solid-state. lasers in the last 10
  • Medical Device Link . The Light Stuff: Optical Imaging in Medical Diagnosis Optical science may light the way to radiation-free tissue analysis.
    sound, the echoes are waves of light emitted initially by a laser that bounce off biological microstructures several millimeters deep in the tissue. A computer converts the returned signals into cross-sectional images by measuring the delay in the echoes. "The advantage over ultrasound is that we have
