Abstract :
Ytterbium-doped materials are competitors of neodymium-doped materials for high power diode-pumped lasers. Furthermore, some materials exhibit ultrabroad emission spectra, which makes them suitable for tunable or ultrafast sources around 1 μm. The high power and tunable cw laser action in Yb:Y2SiO5 (YSO), and then in a composite crystal made of Yb:SrY4(SiO4)3O (Yb:SYS) diffusion-bonded on an undoped YAG crystal. The pump source is a fiber-coupled laser diode emitting 13.5 W at the zero-line wavelength (977 nm for Yb:YSO and 979 nm for Yb:SYS). The resonator is a 3-mirror cavity designed to support only TEM00 oscillation.
