Hi fluff nice peace of art you've got there.
About information on diode it would help if we could see it.
See if this can help:

But remember that Jonoptiks has MTBF as high as 10000 to 50000 hours.
Hope I could Help.

So, to let you all know, its a Kvant product, some variant of the Maxim Range. I say variant because usually the maxim range have scanners fitted.

The unit should be 5W not 4W with a pulsed power of 6W at 532nm. Maybe its got 4W because the diode was dying and meassured 4W

I didnt hear of any Jenoptik heads failing before, this will be the first so I suspect the problem will be in the power units or some guy took it to bits and removed the diode power cables then its likely dead.

One note of caution, do not disconnect any cables from the diode to its power supply or the head will be killed / broken in minutes. These are extreamly sensetive to static, more than a typical device.

If you need help to test it correctly, give me a PM

Thanks for the advice Andy , and the pm's .

looks like they are using a computer power supply...

to test the power supply short the green wire in that harness to ground, should bring up the supply at least

[andyf97]

I hear you got it working, is it true?

[mliptack]

If what Andy says is true - I better see some pictures!

I have to admit - that is a weird layout. Start and stop button on the same side as the aperture - maybe its just me.

I wonder if thats a dpss or thin disk. the new jenlas lasers are thin disk greens. and not too badly priced either. about 10keuro for 8 watts.

[andyf97]

its thin disc not dpss

[buffo]

I would think a thin disc (or active-mirror design) would still qualify as DPSS. After all, you're still pumping the lasing medium with a diode, and you're still doubling the 1064 nm output from the disc with a KTP crystal.

In fact, the disc itself is made of the same Vanadate (or YAG, in some lasers) as you use in a standard DPSS rig. About the only difference is the thinness of the medium and the big honkin' heat sink on the back. (Well, and the diagonal path that the pump energy follows through the medium.)

Really, thin disc is more of a special cavity design than an entirely new laser, IMO...

The question was about this laser technology bein based on dpss or thin disc, so the answer is thin disc.
