摘　　要：Effective diode-pumped continuous wave （CW） tunable laser action of a new alloyed crystal Yb：LYSO is demonstrated. The alloyed LYSO crystal possesses the desirable physical and laser performance of La2SiO5 （LSO）, as well as the favorable growth properties and costs of Y2SiO5 （YSO） in the same time. With a 5 at.-% Yb：LYSO sample, the output power of 2.84 W at 1085 nm and an optical-to-optical conversion efficiency of 54.5% are achieved. Its laser wavelength can be tuned over a broad range of 81 nm, from 1030 to 1111 nm.Effective diode-pumped continuous wave （CW） tunable laser action of a new alloyed crystal Yb：LYSO is demonstrated.
