VDX replied to a thread Dpss yag laser in Advanced Technical Discussion

... for typical power-efficiency with diode pumped lasers, here some numbers: Sometimes around 2005 I had a "disk"-laser with 20Watts averaged, which was pumped with a 60Watt IR-laserdiode-module. Modern fiberlasers too needs around 3x the later "averaged" output power as combined...

Laser57 replied to a thread Dpss yag laser in Advanced Technical Discussion

Ah, 120+ with flash lamp. Best I've come to find for the ND:YAG output of the diode pump driven 300W Avia Thor head is about 40 watts for a single head, but when searching online for typical output percentage of the pumped power for 1064 nm output, estimates are much higher. Appears I have a bad...

VDX replied to a thread Dpss yag laser in Advanced Technical Discussion

... the two old ones (120W/150W) were not DPSS, but flas-lamp pumped ... much lower efficiency, as with diodes -- I'll estimate something like 3-5%, instead of around 35% with DPSS. I've stored one of the resonator chambers and got some water-cooled 405nm-LED's with 9W and 100W output, to pump...

Laser57 replied to a thread Dpss yag laser in Advanced Technical Discussion

You could get 120+ watts out of one single ND:YAG from the Avia Thor when pumped at 300 watts? Impressive, especially 150W. Just wanted to confirm this is possible from a three diode ring Avia Thor ND:YAG, thanks.

Slide started a thread Source for Lenticular and "Fuzz" scan through materials? in Lumia

Not exactly Lumia, but we are attempting to modify a commercially available motorized DMX controlled D/G disk. The Lumia port is pretty good but we would like to swap out a couple of the other effects for a lenticular grating that gives a sort of "3D" effect, and also looking for a Fuzz effect....

Thanks to the folks that helped out with some info on our decision. The OPT Lasers 8000 RGB was great for the price point. The ILDA test pattern looks good, colours are in balance and we added their DMX scan through FX wheel. All works well.

blueUni replied to a thread Advice Needed – Safe Laser Setup for Interactive Art Installation (on a budget) in Help!

The overall project budget is higher, but only about 1/4 to 1/3 would go toward the laser setup specifically. I’ll be working in a blackbox theater with access to video projectors, lighting, sound, etc.—so I’m mostly looking to explore how a laser element could complement that environment. It’s...

laserist replied to a thread Advice Needed – Safe Laser Setup for Interactive Art Installation (on a budget) in Help!

The goal to do an art installation worth the effort with no background in lasers, no knowledge of laser safety, and a budget $2500 seems unrealistic. There's a guy here that does lumia installations that you might interest within your budget, but it would almost certainly be a short run thing....

You could try opening the case and cleaning the scanner mirrors and the dichros, but you need to be very careful, as it's easy to damage the coatings on the dichros, and it's also easy to knock the alignment out of adjustment. While you're in there, go ahead and clean the inside surface of the...
