Abstract

The anisotropy of thermal property in an

Yb, Nd : {Sc}_{2} {SiO}_{5}

crystal is investigated from the temperature of 293 to 573 K. Based on the systematical study of thermal expansion, thermal diffusivity, and specific heat, the thermal conductivity in

Yb, Nd : {Sc}_{2} {SiO}_{5}

crystals orientated at (100), (010), (001), and (406) is calculated to be 3.46, 2.60, 3.35, and

3.68 W / (m \cdot K)

, respectively. The laser output anisotropy of a continuous-wave (CW) and tunable laser is characterized, accordingly. A maximum output power of 6.09 W is achieved in the

Yb, Nd : {Sc}_{2} {SiO}_{5}

crystal with (010) direction, corresponding to a slope efficiency of 48.56%. The tuning wavelength range in the

Yb, Nd : {Sc}_{2} {SiO}_{5}

crystal orientated at (100), (010), and (001) is 68, 67, and 65 nm, separately. The effects of thermal properties on CW laser performance are discussed.
