    (A) Mineral phosphorescence

    Thats really interesting, any idea what is in the cement that is causing he fluorescence? I'll have to try that in my house, I definitely haven't noticed it before!

    (A) Mineral phosphorescence

    I also have a piece of Icelandic calcite and indeed it does not fluoresce, the birefringence is really interesting though! I always show my students when I teach my optics class, you can actually get a similar effect by laminating multiple pieces of glass with different refractive indices :) I...

    STEAM (STEM+Art/Design)

    Thanks, Ill have to check them out! and I'll look into photonlexicon as well. I"ve actually been experimenting with GITD materials and 405nm laser for years! About 10 years ago I painted my bike GITD and made a GITD suit for halloween that year too so that people could write on it and draw...

    STEAM (STEM+Art/Design)

    I didn't come up with the acronym, it already exists and I'm not trying to make them the same thing, just talk with people from different backgrounds and disciplines and see what we can offer each other. I would never claim that my artwork is science or that science is art but my work is...

    Glassblowing

    Nice! Scientific glass work is not easy! I've been working with glass for about 12 years now and its mostly what I do as a profession. I work with soft glass a majority of the time both at the furnace and on the torch but have a lot of experience with borosilicate and some with quartz as well...

    (A) Mineral phosphorescence

    I've been doing this for years, It's a handy tool to have when looking for fluorescent and phosphorescent minerals as well. Calcite is especially responsive and has a reddish/orange glow for almost a full second after the beam passes! I'm guessing this is due in part to the drastic change in...

    STEAM (STEM+Art/Design)

    I get that I posted it in the wrong sub-forum, but theres really no need to be so negative and closed minded. I'm not looking for a 'Laser & Art & School/Playtime Experience' and frankly I'm offended that you would reduce my attempt to start a real conversation about the possible innovation that...

    STEAM (STEM+Art/Design)

    Hi Everyone, I wasn't able to find any threads related to STEAM (Science, Technology, Engineering, Art, Math) so I though I'd start one :) (if there already is a thread or if there is a better place to post this, please feel free to move this post or refer me to an existing thread) For those...

    diffuse refraction of green laser light hazardous?

    Thanks! Thats what I thought and what I was hoping, but I came to get a few more opinions because I am far from an expert when it comes to lasers and I want to be sure theres nothing Im missing.. safety first! Also thanks for the tip for replies

    diffuse refraction of green laser light hazardous?

    GSS Thanks for the encouragement, yes I hope to be a legit member of the group, I'm just off to a rough start (which, I know, was my own fault) haha. I seem to be getting some good responses today though! Encap's links were really helpful as a thorough overview of laser safety and potential...

    diffuse refraction of green laser light hazardous?

    Steve001 Absolutely, part of the issue though is that all of the safety/hazard information I've read is referring to the hazard of the beam itself, or diffuse reflection. Whats happening in this case is refraction, as the beam is passing through a translucent medium and reflecting many times...

    diffuse refraction of green laser light hazardous?

    Alaskan I honestly didn't know and it wont happen again! Those are some great tools in your links, thanks! The divergence calculator is especially useful!

    diffuse refraction of green laser light hazardous?

    RB Astro I totally understand and didn't realize how this forum works when I came in, Its very different than many others I participate in but in a good way. Its nice to see people trying to build a community instead of a free for all with everyone hiding behind anonymous handles. I feel foolish...

    diffuse refraction of green laser light hazardous?

    Hi cyberdoc, Ok I thought so, just wanted to make sure it wasn't in response to the content of this post. I understand and have since read the rules, it was inconsiderate of me to post without doing so beforehand. Needless to say, it won't happen again. It is unfortunate though, that this...

    Hello!

    Hi cyberdoc Thanks for welcoming me to the forum and I'll definitely have to look into the laser artists in this community and look forward to talking to them! Safety is my cheif concern as well and the main reason I am here, I'd like to be confident that any work using lasers is safe for...

    Hey cyberdoc, is that in response to this post or that I double posted?

    Hello!

    Thanks for welcoming me! And yes those are both excellent resources so thanks for those as well!

    My apologies, won't happen again! Didn't mean to cause any offense

    diffuse refraction of green laser light hazardous?

    by the way was it you that posted this on the other thread that was deleted? For comprehensive laser safety information see: Laser Pointer Safety - A comprehensive resource, for safe and responsible laser use (Laser Pointer Safety - A comprehensive resource, for safe and responsible laser use)...

    Hello!

    Hi everyone, I'm new to the forum but I have come across it many times while doing research, glad to have finally signed up and joined the community! I'm an artist working mostly with glass and light and have become fascinated with lasers in the process. My main reason for joining the group is...
