What is the highest power all diode laser projector out there?

64w - 12w y = 52w diode

64W - 12W yellow - 20W 532nm =32W Diode… and it would be purple, not full color.

sorry your right my bad

having spoken to them I know they make high powered 520nm modules also

I'm sure that someone out there either has a higher power all diode or there will be one very soon, just couldn't find it. While looking for high power I did see this guy claim to have a 200Watt Laser all diode, but his photos are photoshopped so I don't really believe it. https://www.facebook.com/photo.php?f...type=3&theater

It's a little bit of a waste chasing higher and higher powers systems with all these diodes; as 9/10 the beam just gets bigger and bigger, as there's a relatively fixed power density you can achieve.
I think of it a bit like the camera "mega-pixel race" a few years back where some cameras boasted 30MP sensors, yet still took relatively poor photos in comparison to a quality 8MP etc.

Hopefully that didn't sound too negative; I just think there's more to a quality laser projector than the "50W / 30MP / 800hp / 6.2L" numbers games.

agreed 100% on this. The power race is getting a bit out of hand. The quality of a beam is neglected way too often these days

Yes bigger beams are picked up better by a crowd at far range.. but it doesn't look as good as a quality beam.. at some point it just becomes a torch.

+ 1 with PJ.

Plus there's the potential safety issue. Fine for everyone on here who knows better than to crowd scan with 52w of power. Unfortunately, there are those out there who don't know better. I personally don't see the use for these huge lasers unless you do outdoor shows in football sized stadiums or at huge concerts or festivals. Other than that, the whole arms race thing is nothing more than I've got bigger than you have.

I've seen a show indoors where there were 5K people and a couple of watts of green audience scanned without competing lighting that was more than enough to impress:




Same venue, different show with a couple of extreme power lasers (suspect were laserscopes). Overhead, but in my opinion both the beam quality and overall brightness which just resulted in a green glow and white hot beams was horrible when compared to the 1st show with much lower power lasers:





Personally, I'll take a safely audience scanned show with no competing lighting everyday over a show with huge powered lasers overhead and competing lighting.

It's probably difficult to tell from the above screen grabs taken from video. But when you see the actual videos, the 1st set of beams are tight and really impress in a perfectly dark room. The 2nd set are fuzzy due tot he high power and cause a diffuse green glow in the fog that somewhat loses the beams.

Quality over quantity.

Not to mention of course that audience scanned shows nearly always look better than overhead shows as there's just far more you can do plus you have that interactions. Obviously not an option for everyone as regulations may get in the way but where it's possible and it can be done safely.....also lets face it, even in the USA there are options if you buy projectors with PASS fitted.

You must have missed the point of these lasers, they are for LARGE INDOOR FESTIVALS, and OUTDOOR EVENTS where high power is required to compete with the HUGE ARRAY OF SHARPIE BEAMS and MASSIVE LED SCREENS. These are not the lasers you bring to the local club, or your buddies 1000 person party. I have dozens of 4-8watt lasers for those events, again, these are strictly for events with over 10,000 people in attendance where high brightness is required.

Rick your lasers are certainly very impressive! I've never personally worked with anything more powerful than a Spectrum 20 and would love to see them in action in person!

I agree. A thin beam looks more laser like. Huge, powerful beams such as from a LS are impressive, but they look different and less elegant. This is not to suggest that slicklaser's beams are fat, just that, tiny hair like beams have a certain look that is appealing just for its "improbable" thinness.

I think the real limit is still the scanners. I am very serious. There has been little progress here, but it is possible. Beryllium mirrors would be expensive, but nowhere near the cost of 50W of laser power. With bigger mirrors (and still fast scanners) the divergence can be reduced and at 10M and 1.3 mrad, a 7mm beam becomes 20mm in diameter and that is starting to get fat, at 25M well...

All the above pictures are from large events.

The room in all the above pictures is 92m long x 22m wide (302 feet long x 72 feet wide approx x approx 40-60 feet high). That is a big room!

Having said that, I take your point. If you're having to compete with other lighting then I understand the desire for higher powers. But this to me is an issue with the event, seemingly most especially in the US, where there seems to be no control over the competing lighting, hence the need for huge powers. Get the other lighting under control and not only do the lasers look better, but you can use much lower powers. Anyway, I diverge, so apologies.
