The transmission ratio exceeded 95% in near-infrared range, so the LCAS:Tm(superscript 3+) glasses can be used as high transmission optical glasses. The integral emission cross-sections outclassed 10^(-18)cm, the fluorescent ratios were higher and the radiative lifetimes were lenger, to the glasses are possible to be used as new laser function materials. The new strong and broad emissive bands for 400nm to 680nm emerge in the emission spectra of the another glasses samples.
