Effective diode-pumped cw tunable laser action of a new crystal Yb3+:Lu2Si207 (LPS) is demonstrated for the first time to our knowledge. The advantage of Yb: LPS is the presence of effective low-symmetry monoclinic structure and its single crystallographic site, which are benefit for the low threshold and high output energy. With a 5-at% Yb: LPS sample, we achieved 2.22 W output power at 1070 nm. And the wavelength could be tuned from l034nm to l080nm.
