The three atomic emission spectra for Ytterbium can be shown on graph bellow: NIST Atomic Spectra Database [1], gfall.dat file from Kurucz CD-ROM No. 23 [2] and AtomTrace database. Lines in the AtomTrace list were observed in the optical emission of laser induced plasmas, and the respective values of spectroscopic constants are taken from [1].
Fig. 2 UV-vis absorption spectra of the Yb complexes with different porphyrin ligands in CH2Cl2. Excitation within the Soret band region at 425 nm yields a typical NIR emission centred at 974 nm for all the Yb ( iii) complexes, which is assigned to the Yb ( 2 F 5/2 ? 2 F 7/2) transition.
There is a very wide range of different ytterbium-doped gain media: yttrium aluminum garnet (Yb 3+ :YAG) (? YAG lasers ): suitable for high-power operation e.g. in thin-disk lasers, with emission at 1030 nm or (sometimes) 1050 nm. yttrium vanadate (Yb 3+ :YVO 4) (? vanadate lasers ): broad and smooth emission spectrum.
