This looks interesting; however I think you need some pictures and/or a video on the page. Also I, and probably many others, simply don't click pdf links from unknown sites without a very good reason.

Thanks for the comment! You're absolutely right that visual aids help a lot, especially for tech concepts. Unfortunately, this is an early-stage patent-pending system, so I can't publish any diagrams or images that aren’t already protected. Also, since Hacker News doesn’t support inline images, it’s a bit tricky to show visuals here. Still, the linked blog post provides a concept summary in English, and I’m happy to answer any technical questions if you're curious!

  Do you have a working prototype?

    The concept has been theoretically validated, and the system is currently patent-pending.I’m now collaborating with an industry partner to develop a working prototype. Happy to go into technical details if you're curious!

      I've read similar projects that use two lasers for microscopy [1]. They build them and used them to get images of cells. So I don't doubt of the general theoretical idea. The devil is in the details. Can it run in open air or the concentration of argon is too low? Can it get enough brightness if you plug it in a standard electrical socket? How safe is it? [2] How many strong lasers escape the device? Does dust cause problems? Does it need a filter and a fan, or you need to enclose it to get clean enough air? How big it is? A tabletop device? Can it be shown to a thousand of people for an big event? Perhaps you can get more traction here with some diagrams that show how it works without revealing all the secret details, but a text only explanation is too boring for the general public. Anyway, I don't expect that this get many upvotes until you have a working prototype and some photos that shows it working. [1] I think it was a German research team that also do confocal and 4pi microscopy. It was a long time ago, so I don't remember the details. [2] A long time ago, I used an optical table that we shared with another experiment with a green 5W (5mW?) laser pointing to me and barrier in the middle and pipes and a lot of equipment. So it was safe, but just in case, never duck to pick stuff from the floor.

        Sure! Here's a very condensed overview: The system uses two intersecting CW lasers in ionized gas to induce spatially-localized visible light emission through multiphoton transitions (non-resonant, no intermediate state). It's designed for open-air operation and uses energy focusing via PWM and low duty cycles to stay Class 1-safe while maintaining sufficient photon density. We're developing a working prototype with an industry partner, aiming for tabletop-to-large-scale modularity. Happy to go into more technical details if you have specific questions.

I've written a condensed summary version as a technical abstract here, in case anyone wants a quicker overview before diving into the full PDF: https://blog.naver.com/as33sa/223833263822 https://blog.naver.com/as33sa/223833263822 This version focuses on the key principles, system architecture, and potential applications. Since the original PDF is quite dense and spans 13 pages, I created this summary to make it easier for readers to grasp the core ideas more quickly. Feedback is always appreciated!
