I think fireworks and lasers go together very well. Beam work in all that smoke is awesome!

I have many pair of safety goggles that came with different lasers but I have eagle pair that cover me for my higher power blue and green toys. Hmmm....I need a high power red one o' these days!

My buddy in the lab confirms this is kind of a weird diode. Below 65 degrees F it puts out something very close to a single mode beam, speckle and all. But as it warms up it's linewidth gets bigger and bigger. I'm still looking up exactly what this means but my lab guy says at 95 degrees F...

Hi Ivan! Try the Tinker Tavern Valkyrie line of lasers. I got a 488nm, but they have many wavelengths to choose from, including yellow!

Have you seen what gallium does to aluminum? 👹😈

We might get up into the swealtering mid 80's later this week.

I'll ask my buddy in the lab @ work to spectro the thing for me. Gonna cost me a six pack though :cool:

Hmm, I wonder if they all use the same diode. One of my go-to visual effects is shining a laser into a big selenite crystal. With a single mode laser I get wicked speckle. With my Valkyrie.......might as well be a bright LED. Compare a good 532 DPSS green through a diffuser to a 445...

Diffusers are great with single mode diodes. Love the trippy look of speckle :-) But this laser has very little/no speckle which is one of the reasons I'm sure it's not single mode. It's either a mystery diode, or that poor little 60mW diode loses it's single mode goodness when overdriven to...

I'll give it a try.

You tell me :-) It also has no discernable speckle at all.

Just press the button on a laser 303 anywhere in my house and you'll have a playful amstaff in front of you in mere seconds. She can hear the switch click!

I don't think the Tinker 488 is the GH04850B2G diode. That's a single mode diode, and my new toy is definitely not single mode.

Nope, it's a direct diode 488. The focus ring is very low profile which makes it a bit difficult to use. If it were a higher power laser I'd have to turn it off to move the focus ring without singing my fingertips. The threads on the ring are a bit loose so when it's unscrewed a bit the ring...

I recently reviewed their 488nm Valkyrie pointer and I'm pretty happy with it. I DO wish there was more technical information on their page though, so I hear you there. But from the things I've read on this forum people seem pretty happy with their purchases. The quality of the laser I...

Weirdest thing I've ever had chase a dot was a wolf spider. This was over 20 years ago, watching the spider chase the dot from a dollar store keychain red across my ceiling..... It felt almost like a pet.....for a few minutes :)

That's how we picked one of our rescues. I dotted the far wall of the room. Three of about a dozen puppies noticed, but only one got up to go check out the 'thing' on the wall. I used curiosity as a proxy for a smart dog. Seems to have worked out well!

I'm a pretty satisfied customer :) If I could have one thing added to the kit it would be to trade one (or all) of the star caps for a cap with a plain AR coated window to keep dust outta those nice clean optics. The collimating lens is sort of 'down in the hole' and isn't going to be easy to...
