Yeah, gonna need to include Sanwu as a seller of beam combining lasers. What’s the deal with XPL these days?

I do think about rear screen (aerial) projections, but it is not my specialty. My projector is optimized for laser graphics, and most of the images in that show are rather complex, dim, or just not rhythmic enough for rear screen projections IMHO. We all have different opinions on what looks...

Didn't mean to make anyone feel bad about not being able to come watch a laser show. No worries, your feedback is plenty. The video does a decent job at displaying the images themselves, but the colors are an order of magnitude less vibrant. I am sure you understand this plight if you've seen a...

Ah yes, Laser Pointer Pro. Is there any camera available that could take a beam shot of that monster in one Picosecond? I wonder how long the warranty is on that thing? Maybe 1/2 a picosecond after switching on? I recall browsing that site a couple years ago. I found this crazy "2 in 1" laser...

I can't thank all of you enough. Your kind words mean so much to me. These shows take so long to get right, and sometimes, I feel like no one will ever be there to watch them. At my age, the clientele are hard to come by or maintain. It fills me with joy that you guys enjoyed it, and I will be...

Thank you, and I am glad you found it interesting. I am indeed very happy with my new projector. I am one of those people who just can't stand flicker in my shows, and this is exactly what I needed to solve that problem. The Saturn scanners also produce a near-perfect replication of the base...

EDIT/UPDATE I'm working on new content. More info soon. For now, here's a preview. -------------------------------------------------------------------------------------------------------------------------- It has been a while since I have been around these parts, so allow me to give a...

No problem, but don't forget that you need to get safety glasses. As for the price, what did you pay? There are many "500" mw Lasers on the site with different prices. I would say that if you paid any more than $30, you were ripped off. You can get 50mw green lasers on eBay for $10 That is not...

I am not familiar with this company, but looking around the site, it just seems like another Chinese wholesaler. Most of the lasers they sell on sites like this are very low quality, and the power readings may be entirely made up. Sometimes there are higher quality products on these sites, and...

Is the diode cavity changing dimensions due to thermal expansion caused by a temperature gradient? I believe that that could cause mode hopping, correct? But wouldn't that just add or subtract various lasing modes, thus making the output more or less "Multimode" without actually splitting the...

Interesting stuff. I had no idea that mode hopping could be observed in diode lasers, but that video imbeded above certainly proves it. Is it caused by high drive currents? Flaws in the semiconductor cavity? I haven't observed it in any of my solid state pointers but then again I haven't been...

As amazing as that would be, I think it probably is not worth sanwu's time to align the laser so precisely, especially considering the slightest knocks brought about by shipping would render all of that work useless. I think they should use a design where it comes aligned "adequate for use", but...

Great call asking for input from potential customers. Most of the suggestions I would make have already been accounted for, but I might as well reiterate. 1: please please please make sure aligning the unit is something the customer can do, ideally as easily as possible. Working with...

Thanks guys. I also think that RGB unit is VERY tempting. I would be lying if I said I hadn't thought about an rgb handheld unit many times already. Certainly a unique and worthy edition to the Sanwu lineup.

Cool review! would definitely take the advice and make sure the battery is very secure in the laser. I have noticed that even high-quality pen units can quickly develop this issue. Also makes sense that you are seeing instability. they are old, and WL isn't exactly known for stable Dpss units...

1: A Mini Spiker with all standard diode wavelengths (635nm, 445-450nm, 465nm, 520nm etc.) with power levels available up to 5 watts. May also have the option for lower power 480, 485, and 505nm diodes. 2: An "Extension Tube" which attaches to the head of the Spiker saber, shortening it and...

To Be fair this is an old post, White Fang hasn't been online since 10/17. Still, laser visibility information is fairly common.

Congrats, won't be long to 10k now :) If I had a mw for every time you posted, I'd have a severely overdriven nubm44!

If your impressed by that laser, get a 638nm. Much more visible color. I wouldn't buy it from laser pointer pro though, they are notorious around these parts. You may even consider building it yourself.

Sure it's worth the effort? Having payments held off for over a day is awful suspicious. Then again, wouldn't a scammer take the money and run? Interested to use your experience.
