NIR emission from a DYAG crystal

QuantaMaster 50 emission from DYAG crystal
NIR emission from a DYAG crystal Nd-doped glass measured with the NIR-InGaAs. High sensitivity of the instrument permits the use of narrow slits on the emission monochromator and the resolution of narrow spectral lines of DYAG.


Singlet Oxygen
