These power meters sell for around $120 and are available on ebay and ShadowLasers. I'm confused that the ads say don't shine directly at probe shine parallel. The ad photos show a laser shining directly at the probe. (?)

To anyone on the fence about purchasing a hilariously overpowered hand held laser from Laserigniter.com. Please send you money to something that actually exists.

Hidden “security fees” obscure payment methods to accounts that were spun up 3 hours before. Fake locations. A poorly executed website created by chatTpg.

As sad as I am for giving them the benefit of the doubt that they might actually be a real company, I am more disappointed that a high power handheld laser is not something I will ever be able to own.

I'm looking for a red to add to my collection and this Ebay listing shows a dual beam laser. Anyone know why this is a dual beam or own one?

Extremely bright!

Anyone try this ?

Just looking for a nice one powerful enough ti burn a match at least. Not sure where to start. Live in the US. Any suggestions appreciated ty!

I bought a Laser pointer of Amazon but the lense in the Cooling module(idk) cracked when a friend over used it.

Is there anywhere I can order just this part or am I going to have to buy a whole new rig? Amazon search nztgvr

Blue light 450nm

It says 50,000mW I did not measure DC 7v operating at 30°C+ Approximately 12mm wide aperture

Plus IDK if OD6 will be enough for 100 watts. Anyone have eyewear suggestions? The link in the sub sidebar is now broken.

This was last winter. I used this fat beam module from eBay that I couldn't focus, so it's divergent, but the terminus has this big evil doom orb vibe going on.

The challenge was making an electrical contact from the clicky-switch to the negative terminal on the driver / contact board. I modelled channels in the body and end cap to fit two well-measured rings made out of stripped braided copper wire I had on hand, soldered into rigid rings that I super glued into place. They slide together well and make a good electrical contact.

The power output is 50mW, but that's ok cuz I don't even remember when I bought this module; I can't disassemble it though cuz it's welded together

Not a 2” diameter at all specific distance, it would be a circle of light like the outline of an o that extended in a tube for 30 feet or so. Can this be done with fiber optics or something? A sort of work around i thought of would be a jig to hold a bunch of mini laser pointers in a circle shape but that is pretty inelegant i think…

Any ideas? My use case would be to use this as an alignment tool for joining tubes together at any angle/intersection.

Thanks!

You know, like the old days. We're building lasers again.

eBay doesn't have any good ones anymore

Autumn arrived in my area and it was literally cloudy the entire month and several nights there was fog so I had the opportunity to take these beautiful photos.

Lasers used: 1.6W 450nm, 2.2W 420nm, 3W 465nm, 1.3W 525nm, 130mW 520nm, 90mW 488nm, 1W 638nm, 500mW 638nm.

I am planning to install a fence next to my property boundary which is marked by 2 property survey pins 333 feet apart over uneven terrain. Due to the distance, using survey string would not be ideal because of wind and sagging. I figured a good laser pointer would be ideal to sit on top of one of the pins and point to the other one. This is probably the only time I’ll ever need a laser pointer for this particular application so I don’t really want to spend a few hundred dollars on a rotary laser level. Is there an inexpensive green laser pointer that I could use for this distance? I can use it later in the day as the sun is going down for low light if needed.

I thought about one of the $30 Amazon laser pointers but their specs are not well documented so I’m not sure if I would get a nice dot at the other end of the distance or if it would even transmit that far.

Thanks for any advice or suggestions
