脉冲压缩透射光栅
脉冲压缩光栅最重要的性质是衍射效率高和低的波前变形,面向光栅的多通使用要求。激光脉冲压缩传输光栅基于LightSmyth破纪录的透射光栅平台。优化的线性P-偏振衍射效率在94%以上,它可以让我们的客户最小化系统光学损耗,尤其面向高能激光器。
优点
- 对指定的偏振有特殊的衍射效率
- 宽带和低角度的敏感性特殊设计
- 超抛光石英基底使波前变形最小化
- 使用熔融石英和高可靠介电材料
- 不使用聚合物或有机材料
- 每个光栅均为超低散射母光栅
应用
- 皮秒和飞秒脉冲压缩
- 高功率激光器
- 频谱合成和光束控制
- 远程光学传感器和光谱

N/A |
1 Grating will perform with high efficiency over significantly larger spectral range and range of angles- please inquire. |
2 P-polarization: electric field vector is perpendicular to the grating lines. S-polarization: electric field vector is parallel to the grating lines. |
3 Worst case in the operational wavelength range for optimal polarization. |
