It was in Mexico. Reporting was from the UK edition of TheSun.

Bigger the better. SG, VT, or DRSS TC?

Bot?

I'll second that thought Paul. The video clearly shows no lasing going on and the discharge color is wrong for HeNe. It looks like a cool neon tube for an art project though.

WTAF?

Why do you need a laser that far into the infrared? A 3 watt beam you can't see is something you need to be VERY careful with.

i'll keep that in imnd if I win :)

Cute lil' thing :-) How is the duty cycle?

https://dtrslasershop.com/collections/dtrs-glass-lenses I'd try the G8.

I'll let the laser CNC guys correct me but IIRC a longer focal length focusing lens will give you a longer 'blade'. The zone where the beam is narrow enough to do what you're after. But a shorter focal length lens can provide a smaller focused 'dot', but with a very short 'blade'. Being a...

I'm a subsccriber Avery. Thanks for all you do!

My issue was fixed, thanks! You might want to help out Bowtieguy as he seems to be having the same problem I had. Does Avery need to fix each account individually or is there a way he can grep all the donors and fix them all at once?

One can hope :-) Sniveling to the mods/Avery seems to have worked for me. And I still see ads on the site but I'm not getting the full page pop-ups anymore so.....win!

You did clean your lens. Unfortunately acrylic lenses are very fragile and cleaning damaged it. New lens or new laser.

Given the parameters you've specified for the material and the size of the holes I think the BDR209 diode may be your best bet. It's a single mode diode that can be focused down to a very fine point and has enough power to punch holes in paper with ease. They can be touchy about current so I'd...

Thanks Avery!

If I have to live with a few ads, well, that's what I have to do. But I want my 'Site Supporter' tag back!

Your lens, and possibly the output coupler, are toast. Plastic lenses are very fragile and that last photo looks like you may have gotten some solvent or cleaning fluid under/onto the output coupler. How expensive was your pointer? You might be better off getting a new one.
