Lol sorry, I should’ve posted a better thought out caption but had to get back to work. I know it’s not a laser in the pic, nor is it dangerous. What I meant was that if we started doing that with lasers, it could be a different story

Are you thinking of the same bad idea I’m thinking of?

Oh I’m curious about the 425nm, how does it compare to 405/445? Awesome collection

Just a vague question that crossed my mind and left me curious as to what other members would have to say. I own a few lasers in the 100-200mW range and they sort of occupy a space that's too powerful to be safe, but not powerful enough to pack a punch. Mostly pretty to look at (outdoors) or...

Not too hard to find

Where is this laser from? 532 DPSS if they are made well have an in-built IR filter to block invisible IR wavelengths leftover from the DPSS process. So if you want to check the safety of your laser and whether it’s DPSS at the same time, you could get laser glasses that block green light and a...

I shop for glasses at NoIR Laser, which Laserglow has been known to source their glasses from. https://www.noirinsight.com/laser-safety-eyewear/lenses It's very nice, you can filter by desired wavelength, OD, and CE certification (select yes). Then when you find good safety lenses, they offer...

Unown posted a nice workaround here Looks good! My first laser was a 5mw 532nm but from Radioshack, there’s something awesome about that beam. I can’t tell how much the alignment is off from the host in the picture, what angle would you say it’s off by? It’s normal to be off by a degree or a couple

With a build like the challenger II I would trust it for several minutes, but I wouldn't leave it on much longer than that. It's a high quality build with a nice heat sink but it's still a multiwatt diode stuffed in a small handheld. Try feeling the heat of it yourself when it's on for a few...

Welcome DonkeyStonky, glad you're happy with your purchase! Any pictures including the box and/or beamshots would be lovely

How will you be using the laser? How is the duty cycle of importance to you? (e.g. you have to keep it on for 3 mins at a time)

Those beamshots are beautiful. The divergence looks so tame compared to the commonly available 465 alternative. Awesome diode

They sell 1W and higher 808nm lasers at jetlasers https://www.jetlasers.org/pl-e-pro/20-pl-e-pro-808nm-infrared-lasers.html#/1-finish-black/50-battery-no/110-series-pl_e_mini/49-goggles-no/34-power_levels-1w I have a 1.1W 1064nm from them, it's very nice for high power near-TEM00 output in a...

psst... now turn it into a 577nm GLP and post it in the sell section for $2000

Thanks everyone!! I almost mentioned the part where they came to visit but thought no one would believe me

I was out the other night taking long-exposure photos of my lasers and the stars, so I thought why not both? Left-to-right: 635nm 50mw (DL Viper), 589nm 20-100mw (DL Spartan), 520nm 50mw (Sanwu Pocket), and 485nm 42mw (small steel host build purchased from a member on LPF). :)

Great idea. I wonder if we’re thinking of solutions for problems they haven’t run into yet — “They only showed 50 meters of [guiding] length, and most lightning channels are kilometers long” — or if they’ve already implemented something like this. They don’t specify whether that 50m is near the...

>> Article Here << If my understanding is right, the high-intensity laser pulse blasts a pillar of air particles out of the way, and that low density air pillar becomes the lightning rod. Just nuts The light energy itself isn't conductive of course, but this is a pretty cool almost-direct...

Attempt at an indoor beamshot: Pics in daylight: This laser focuses down to a pin point for cutting/burning purposes. It's not quite on par with 1W+ handhelds, but it packs a punch and works nicely for applications that don't need that much power. I've used it for engraving hard black...
