    I've been working with a pre owned Kvant Cm1800 and notice a sort of light cloud form when I emit single beams. I cleaned the external window, but I think it may be something internal.. I attached an image below. i have also noticed that the beam seems to curve when I project a vertical line...

    Hi all, I’m new to lasers and planning an interactive art installation in a 40' x 40' x 12' room. The idea is to use lasers and mirrors to create walls or cones of light, similar to: https://www.youtube.com/watch?v=0DFXj6gFsjM ...

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....

    I have a lot of 35W 975 nm fiber modules which were sold as tested and good, the ones I powered up were, but I don't use lasers for anything practical, just for fun and still have two eyes too. I live out in a very rural area and have room to play, no airports anywhere near me but also not pointing...

    What else to do with 1064 nm :p It's a long term project, but I have a few of them...... I made a SHG once before using 1064 nm out of a 15 KW peak power pulsed YAG, average power was only a few watts at 1064.

    I have a lot of laser junk, mostly good parts, but no lasers which produce more than 10W at 532 nm. Would like to use these heads, have three of them, to build a high power 532 nm laser using one or two if OSC and PA arrangement.

    ... interesting design -- round 20 years ago I've helped to assemble the "ringfocus-laser", where 80(!) 20W-Diodes were collimated and the beams combined into 1.6kW on a "spot" roughly 6mm wide for metal welding. Actually I have many IR-Laserdiodes with up to 40W fed through 0,1mm-fibers or...

    There are three 100W ring diode pumps in one ND:YAG head for this one, so that's 300 watts of IR pump into one YAG.

    ... with 100Watts pump power in a DPSS setup with AOM modulation the estimated pulse-peak-power should be something like some 10 to 100 Kilowatts and the averaged "CW" power is highly depending on the cooling methodes :cool:

    Pulsed high current DC to the diodes, I don't have a power supply capable of doing so but for now, want to use them at a constant current with a AOM or something to produce short bursts, high peak power out of the ND:YAG to produce more efficient SHG conversion to green. I was wrong about the IR...

    ... sounds reasonable :cool: On the other side - when only shortly activated (and with massive cooling), diodes can be "overpowered" with up to 50% for some millisconds and up to several 100% for microseconds ... then they'll need some seconds for cooling down. So for "pulsing" applications...

    The donut diode rings are each 100 watts, I believe this is likely DC watts into the diodes, three 100 watt rings producing 300 watts at 50% efficiency would be 150 watts of IR pump power, so it stands to reason the output of the ND:YAG is 1/3, or 50 watts, perhaps 60. Is my reasoning valid?

    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...

I've stored one of the resonator chambers and got some water-cooled 405nm-LED's with 9W and 100W output, to pump...
