The laser was operated at this level for over 45 minutes (∼3 · 105 shots) in two separate runs with a rms energy stability of 1%. The laser was also operated at 7 J, 100 Hz for 4 hours (1.44 · 106 shots) with a rms long-term energy stability of 1% and no need for user intervention. To the best of our knowledge, this is the first time that long-term reliable amplification of a kW-class high energy nanosecond pulsed DPSSL at 100 Hz has been demonstrated.

Bridging light and electrons in TEM
A team of scientists at EPFL and the Max Plank Institute has brought nonlinear optical phenomena into a transmission electron microscope (TEM), a type of microscope that uses electrons for imaging instead of light. The study was led by Professor Tobias J. Kippenberg at EPFL and Professor Claus Ropers, Director of the Max Planck Institute for Multidisciplinary Sciences. It is now published in Science. #nanotechnology #materialsscience #microscopy #optics #engineering #technology #research

Woohoo!!! Feeling proud to introduce one of the silent champions of mankind. 🤗 Research is the backbone of the world that we live in. It takes passion, patience and optimism to discover and uncover truths and eventually make it available for all. Congratulations to my dear husband Abhishek Nanda on unlocking one of his major milestones in his PhD journey. 😍 His paper on "Exploring the fundamental limits of integrated beam splitters with arbitrary phase via topology optimization" has been published as Editor's Pick in Optics Letters. 👏 For anyone who wants to gain insights on the topic, feel free to check out the link below: https://lnkd.in/gANq4e72 🧠 #celebratewithus #nanophotonics #quantumoptics #beamsplitterphase #topologyoptimization #integratedoptics
🌟 PhD Milestone unlocked! 🌟 Dear connections, It gives me immense pleasure to introduce you to our recently published paper (highlighted as Editor's Pick) in Optics Letters. The paper discusses “Exploring the fundamental limits of integrated beam splitters with arbitrary phase via topology optimization”. Here, we design symmetric beam splitters for several combinations of loss and phase within the theoretical design space, while accounting for fabrication constraints. Link to the article: https://lnkd.in/gANq4e72 This would not have been possible without the immense guidance and support of Antonio Calà Lesina and Michael Kues. Thank you for always being enthusiastic to explore multiple dimensions of new ideas and being flexible in our way of working. I would also like to appreciate our teammates in Computational Photonics group for their academic support and my wife Swikruti Das for her mental support. Lastly, I would also like to take this opportunity to thank my parents back in India, without whom I would not be where I am today. Please feel free to go through the article. I would appreciate any feedback, inputs, and arguments that would help boost our scientific community on this topic.

📣 Check out the new EHAWEDRY #research on hybrid muscle mechanics! Scientists are investigating how nanoporous silicon, infused with polypyrrole, behaves like muscles in water-based electrolytes. Using advanced techniques like x-ray diffraction and electron tomography, they discovered that the material's response is complex. Despite having isotropic mechanical behavior, the alignment of nanopores leads to different reactions in different directions. This isn't just a simple cylinder setup; it's intricate and heterogeneous. They also found that factors like diffusion and plastic deformation play crucial roles in the material's behavior. This study shows how combining microscopy and X-ray techniques offers a powerful way to understand these materials at a microscopic level.
