铒玻璃 (Er Yb Glass)

我司的Er,Yb:glass玻璃产品,又称铒玻璃,是一种综合性能良好的激光玻璃。Er3+ , Yb3+共掺杂磷酸盐玻璃(Er, Yb:磷酸盐玻璃)是一种众所周知且常用的活性介质,它发射的激光在1.5 – 1.6微米的“人眼安全”光谱范围内。1540nm激光器正处于人眼安全和光纤通信窗口的位置。这就导致了激光的产生和信号的放大。1540nm激光器已广泛应用于测距仪,雷达,目标识别等领域。磷酸盐玻璃结合了4I13/2Er3+上激光能级 的长寿命(~8 ms)激光能级和与Yb3+共振的低寿命(2-3 ms) 2F5/2激发态。从4I11/24I13/2的快速非辐射多声子弛豫由于分别在2F5/24I11/2 能级激发的Yb3+和Er3+离子之间的相互作用,能级大大降低了反向能量转移和上转换损失。Er3+/Yb3+共掺磷酸盐玻璃作为LD泵浦的1540nm人眼安全辐射源,可发射直接用于激光测距仪和电信通信的人眼安全1540nm激光辐射。具有1540nm波长的辐射输出的Er,Ybglass激光器不需要添加额外的组分。Er3+/Yb3+共掺磷酸盐玻璃激光器是一种人眼安全波长激光器。由于其体积小、成本低而备受关注。EAT14:Yb3+,Er3+共掺磷酸盐玻璃,适用于高重复频率(1-6Hz)激光二极管泵浦1535nm激光器。在这种EAT14玻璃中可以实现高Yb3+掺杂。
