Just had to stop by to admire this legendary level necroposting

My first pointer was a cheap ~650nm 1mw reading light/laser combo from probably 2009. The next was a 5mw 532nm pointer from RadioShack in 2010 and it was so exotic to me lol

Wow thanks for the infographic. This is really cool, it says the gyrotron wavelength will vaporize rock below while passing right through the particle clouds that it generates during the process, minimizing diffusion. Went ahead and checked out the company's main website (quaise.energy) too out...

Hi Dusty :)

I asked Francis and learned the adapters for their handhelds are in fact sized M11.4x0.95. Might need to wait to purchase from Sanwu or make a custom order somewhere

Welcome. Yes greens are more visible than other wavelengths when other variables are held constant, but your assumption about power isn't correct. Visibility yes, power no. Also make sure you invest in some good safety glasses for the wavelength of whatever you purchase. Check here...

Haha thank you. Yes that's fair I could have just looked it up. Just need to confirm that a P0.5 M9 lens will fit a Sanwu host. All threads besides Pocket are same size, around 9-10mm. I obviously have minimal experience purchasing laser lenses, so I don't want to go and purchase the wrong...

bump

If anyone has a spare they wouldn't mind parting with, I'm willing to buy. I'm avoiding purchasing from Sanwu directly due to the covid situation over there right now. Want to be able to illuminate a plane cross section of some substances for fluid dynamics work. Looking for fast domestic...

"big boss" the megamaser. Now that's a name

Would be a cool find, good luck

Average shipping day at DHL

The vets here may not be the most beginner friendly but they will make sure you don’t leave missing an eye. Give and take

This made me reevaluate my reply a bit.😅 I’ve been in this hobby for a while and still don’t want/own a 7W capable laser. It’s definitely not for beginners. I was just trying to be realistic since op seemed mature and tired of the “preachy” answers + genuinely scared of the 7W and rightfully so...

If you got the 7W striker, you probably wouldn't need the flash paper to light a fire. You might need to get closer than 10ft due to the high divergence of the diode though. You are correct about it being incredibly dangerous but it's not like a "nuclear weapon" lol, if you're going to be...

I saw some while making this post so i almost ditched it but thought ah what the hell... https://www.laserdiodesource.com/shop/1300nm-10mW-TO-can-Quantum-Dot-Fabry-Perot-QDLaser https://www.aptechnologies.co.uk/LDs/QD I haven't asked for a quote so I figured affordability might still be out of...

Your post got me good! Still waiting on the GB for those 585's what's taking so long 🤣

Exciting News for the Laser Hobbyist Quantum dot laser diodes have been long sought after for their promise of superior emission quality and wide range of available wavelengths. But due to the complexity of using quantum dots as a gain medium and lack of incentive for mass production, they...

If you focused a laser behind the glass you might be able to ablate the black ink on the sticker and attempt to make it unrecognizable, but hard to tell what would happen without trying it

I agree with not using glasses to point it in the sky but indoors and burning? Even if the close light doesn’t hurt your eyes (which it could even if you don’t notice it) it’s just too risky for me. Light is instantaneous, if you don’t realize there’s a piece of glass next to your target and...
