Ke laser e tiileng ea mahlo e sireletsehileng ka mahlo e nang le 1535nm output wavelength.E na le likarolo tsa molumo o monyenyane, tšebeliso e tlaase ea matla, ho tšepahala ho phahameng le botsitso bo botle, mefuta e fapa-fapaneng ea mocheso, e bontšang hore ke laser e sireletsehileng, e sebetsang hantle le e tsitsitseng e sireletsehileng ea mahlo.
E amohela LD pumped erbium laser e nang le 1.4 ~ 2.0μm leihlo le sireletsehileng la wavelength, boleng ba eona ba optical bo haufi le boleng ba moeli oa diffraction.
