紫外Ce^（3＋）：LuLiF_4晶体激光光谱特性的研究

Laser Spectroscopic Property Research on Ultraviolet Ce￣(3+): LuLiF_4 Crystal

Ｃｅ３＋：ＬｕＬｉＦ４晶体被证明在紫外区域具有较大的增益光谱宽度，这点对于短脉冲激光应用非常有吸引力。我们获得了较大的小信号增益，大于６ｄＢ／厘米。而且，在共焦四程放大结构中，对连续的氦镉激光的增益达到２０ｄＢ。

Ce3+: LuLiF. is shown to have a broad gain spectrum, which is attractive for shortpulse applications. Large small-signal gain over 6 dB/cm was observed for 10--nsec probepulses under KrF--excimer laser pumping. In a con focal 4-pass configuration, 20-dB gain wasdemonstrated for CW laser light.
