Abstract

In this work, the study of the lamp pumped YLF-Er laser operated at four spectral ranges around 0.85, 1.23, 1.73, and 2.84 (mu) under comparable conditions are presented to clarify the possibilities of creation of multi-wavelength lasers, in which erbium doped yttrium-lithium double fluoride crystals (LiYF₄-Er or YLF-Er) have been used as lasing media. Characterization of the YLF-Er multi-wavelength lasers are given, and the thermo-optic studies and second harmonic generation (0.425 (mu) ) of 0.85 (mu) YLF-Er laser emission have been performed. The laser properties of the three types of YLF-Er lasers from a series of new laser systems are presented: the single-wavelength 2.84 (mu) YLF-Er laser, the two- wavelengths <<blue>> YLF-Er laser operating at 0.425 and 0.85 (mu) , and the multi-wavelength YLF-Er laser generating at 0.85, 1.23, and 1.73 (mu) . The laser action of different wavelengths on the biological tissues are discussed.
