水晶类型: Nd:YAG AR 涂层: Uncoated
1964年,贝尔实验室首次演示了掺杂三价钕的钇铝石榴石作为激光增益介质的操作[1]。今天,Nd:YAG已经在固体激光材料中取得了主导地位,成为世界范围内使用较广泛的激光介质,应用于医疗、工业、军事和科学市场。Nd:YAG激光器通常发射1064nm的红外光,但也使用940、1120、1320和1440nm附近的其他跃迁[2]。在SM,我们专注于高纯度低损耗稀土掺杂YAG激光材料的生长和制造。SM的研究带来了许多发现,使激光材料表现出更高的效率、更大的输出功率、更高的抗损性、更低的热透镜效应、更高亮度和更高TEM00输出。我们为您的大批量生产或小批量开发工作提供激光棒、平板、光盘、无源Q开关和YAG光学器件的定制制造。

水晶类型: Yb:YAG AR 涂层: Uncoated
掺杂三价镱(Yb3+)的晶体在紧凑、高效的二极管泵浦激光系统中显示出巨大的应用潜力。[1-4]Yb3+离子只有两个流形,基态2F7/2和激发态2F5/2,它们相隔约10,000cm-1。因此,Yb3+掺杂材料具有有利于高能量1µm激光系统的光谱和激光特性。特别地,Yb3+掺杂材料不应遭受浓度猝灭、上转换或激发态吸收。Yb3+离子还具有很长的能量存储寿命(通常是相同基质中Nd3+的三到四倍)和非常小的量子亏损,这减少了激光过程中的热量产生。在基质材料YAG的特定情况下,Yb3+的存储寿命为950µs,量子亏损仅为8.6%。Yb3+:YAG还具有940nm的宽泵浦线,其比Nd3+:YAG中的808nm泵浦线宽10倍,使得系统对泵浦二极管波长的热漂移不太敏感。这些材料特性与940nm长寿命InGaAs泵浦二极管的发展相结合,使该材料成为二极管泵浦高能激光器的优秀候选材料。据报道,基于SM的升级Yb3+:YAG激光器系统的CW输出功率超过430 W,[1]准CW输出功率为600 W,[4]光光效率为60%。[2]据报道,此类系统可在千瓦级的输出功率下进行缩放。掺杂Yb3+的YAG晶体可以从1%-100%的各种掺杂剂浓度获得(例如镱铝石榴石-YbAg)。
