- This Letter introduces a polarization phase-shifting Newton interferometer that can be utilized for plane optical surface measurements, a setup constructed to realize the interferometer, and the experimental results from...
- Adaptive slit beam shaping for direct laser written waveguides
[作者：Salter, PS; Jesacher, A; Spring, JB; Metcalf, BJ; Thomas-Peter, N; Simmonds, RD; Langford, NK; Walmsley, IA; Booth, MJ,期刊：OPTICS LETTERS, 页码：470-472 , 文章类型： Article，,卷期：2012年37-4]
- We demonstrate an improved method for fabricating optical waveguides in bulk materials by means of femtosecond laser writing. We use an LC spatial light modulator (SLM) to shape the beam focus by generating adaptive slit...
