Abstract：

A　0.56　at.%　Nd:CaMgSi2O6　single　crystal　was　successfully　grown　by　the　Czochralski　method,　the　crystal＇s　polarized　absorption　spectra,　fluorescence　spectra　and　lifetime　were　investigated　in　details.　Based　on　J-O　theory,　the　line　strengths,　spontaneous　transition　rates,　fluorescence　branching　ratios,　and　radiative　lifetime　were　ob-tained.　The　strong　and　broad　absorption　band　at　around　803　nm　matches　well　with　the　emission　wavelength　of　AlGaAs　laser　diodes.　There　are　three　strong　emission　peaks　located　at　1055,　1081,　and　1115　nm　in　fluorescence　spectra.　A　laser　output　power　of　0.262　W　at　1055.25　nm　with　the　slope　efficiency　of　16　%　was　obtained.　The　intense　multi-wavelength　emissions　from　the　Nd:　CaMgSi2O6　crystal　indicate　that　such　a　crystal　could　be　used　advantageously　for　a　multi-wavelength　laser　operation.
