Abstract

3D printing has become a widely used technique for manufacturing micro-optical components for sensing, measurements, biomedical and quantum technologies. Hence, knowing the maximum usable power or damage thresholds of 3D-printed micro-optics becomes crucial. Here we present a first study of the damage threshold values of the IP-S photoresist under high-power cw-, fs-, and ns-pulsed laser radiation with wavelengths in the NIR range. We also study the differences between visual evaluation using bright-field microscopy, DIC-microscopy, and beam-profile damage detection. Finally, we present several application-inspired use cases of 3D printed fiber micro-optics, reaching 10.5 W output power of cw-radiation at 915 nm and 4.5 W and 550 fs pulsed operation at 1040 nm.

高功率激光辐射对3D打印微光学聚合物的影响

3D打印已经成为一种广泛应用于制造传感、测量、生物医学和量子技术的微光元件的技术。因此，了解3d打印微光学的最大可用功率或损伤阈值变得至关重要。在这里，我们首次研究了IP-S光刻胶在波长在近红外范围内的高功率cw, fs和ns脉冲激光辐射下的损伤阈值。我们还研究了使用明场显微镜、dic显微镜和光束轮廓损伤检测进行视觉评估的差异。最后，我们提出了几个应用启发的3D打印光纤微光学用例，在915 nm处达到10.5 W的微波输出功率，在1040 nm处达到4.5 W和550 fs的脉冲输出功率。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
