This paper reports the growth, mechanical, thermal and spectral properties of Cr(3+):MgMoO(4) crystals. The Cr(3+):MgMoO(4) crystals with dimensions up to 30 mm×18 mm×14 mm were obtained by TSSG method. The absorption cross-sections of (4)A(2)→(4)T(1) and (4)A(2)→(4)T(2) transitions are 12.94×10(-20) cm(2) at 493 nm and 7.89×10(-20) cm(2) at 705 nm for E//N(g), respectively. The Cr(3+):MgMoO(4) crystal shows broad band emission extending from 750 nm to 1300 nm with peak at about 705 nm. The emission cross-section with FWHM of 188 nm is 119.88×10(-20) cm(2) at 963 nm for E//N(g). The investigated results showed that the Cr(3+):MgMoO(4) crystal may be regarded as a potential tunable laser gain medium.
本文报道了 Cr(3+)：MgMoO(4) 晶体的生长、力学、热学和光谱性质。采用 TSSG 法获得了尺寸可达 30mm×18mm×14mm 的 Cr(3+)：MgMoO(4)晶体。在 E//N(g)方向上，Cr(3+)：MgMoO(4)晶体的(4)A(2)→(4)T(1)和(4)A(2)→(4)T(2)跃迁的吸收截面分别为 493nm 处的 12.94×10(-20)cm(2)和 705nm 处的 7.89×10(-20)cm(2)。Cr(3+)：MgMoO(4)晶体表现出从 750nm 到 1300nm 的宽带发射，峰值位于约 705nm。在 E//N(g)方向上，FWHM 为 188nm 的发射截面在 963nm 处为 119.88×10(-20)cm(2)。研究结果表明，Cr(3+)：MgMoO(4)晶体可能是一种有前途的可调谐激光增益介质。
