We report an Yb:Sr 5 (PO 4) 3F (Yb:S-FAP) laser emitting at 985 nm intracavity pumped by a 912 nm diode-pumped Nd:GdVO 4 laser. A 808 nm diode laser is used to pump the Nd:GdVO 4 crystal emitting at 912 nm, and the Yb:S-FAP laser emitting at 985 nm intracavity pumped at 912 nm. With incident pump power of 17.5 W, intracavity second harmonic generation has been demonstrated with a power of 131 mW at 492.5 nm by using a LBO nonlinear crystal. © Pleiades Publishing, Ltd., 2012.
