Abstract : The technological status of the erbium laser is described. When a glass base is used, this laser emits energy in the neighborhood of 1.54 micrometers, which is in the so-called eye-safe region of the spectrum. It has been found that a close-coupled arrangement of the laser rod and a linear flash lamp gives the lowest pump threshold energy. The emission characteristics of the erbium laser which uses a phosphate glass base have been determined. Factors affecting the transmission of energy of this wavelength in the atmosphere are discussed. (Author)
