Effect of Yb doping on the crystal structure, polarization dependent optical absorption and photoluminescence of Yb:YVO4 single crystal grown by optical floating zone technique

Spectroscopy properties and high-efficiency semiconductor saturable absorber mode-locking operation with highly doped (11 at.%) Yb:Sr3Y2(BO3)4 crystal

“…Not long ago, the growth, spectra and CW laser properties of 3 at.% Yb 3+ :Sr 3 Y 2 (BO 3 ) 4 (Yb:SYB) crystal were reported in our laboratory [15]. Generally, Yb-doped gain media allow a high doping concentration, which may be beneficial to obtain high-efficiency lasers [7,8,11,13,16,17].…”
