Cr3+:MgWO4 crystal was grown successfully by the top-seeded solution growth method.
Cr3+:MgWO4 crystal has weak anisotropic thermal expansion and large thermal conductivity.
Cr3+:MgWO4 crystal has broad and strong absorption and emission bands.
The results show that Cr3+:MgMoO4 crystal is a good potential tunable laser gain medium.
