Finally NEW KVANT 532nm modules developed!

[badger1666]

dont shoot the sales rep just yet
they have only just finished building and testing it
martin is a sales rep for kvant he dont know all the super tech stuff
give him a chance to get the info from kvant ,not bite his head off
because he does not have the answer within 30s of posting
more info will come in time

^Pelosh (being the salesperson that he is) should have had the tact to post exactly that, then, rather than the unprofessional response in post #7..

Good idea DZ!. Either one of them should be able to give a unit a thorough evaluation. Modulation characteristics would be of considerable interest to most of us.

These modules are going to be shown at Frankfurt this month so everyone is welcome to visit us there. We might consider sending one of those to Tocket after that although I'd like to know how many other modules from other suppliers he tested before some of you were satisfied

What's wrong with getting right tech. info from developers and getting it here by tomorrow?

[tocket]

Thanks for the kind words. I haven't actually posted many results, because all the DPSS lasers I've tested so far look so poor modulation-wise that I don't have much nice to say about them, and before I give them thorough public bashing I'd like to be very sure of my results. One chinese manufacturer is about to have it though (especially since I sent it back for service without them fixing it).

I am very curious about the modulation characteristics of these new KVANT modules. Unfortunately I am rather busy at work until mid-April, so it would be hard to evaluate it before then. I'd love to for once be able to recommend a DPSS laser though (it has yet to happen).

Regarding the M² of cheap chinese lasers, I suspect they don't actually measure it. At least not properly. I don't trust it.

[ElektroFreak]

The only ones I sort of trust are CNIs.. They quote an m^2 of <2 on all their high-powered systems. That my even be a bit low, but at least they don't indicate a near-perfect beam at those power levels.

DPSS is full of flaws, that's for sure.. but for us normal folks it's about all we can afford.

[tocket]

I'd like to think that there are nice DPSS lasers out there. Sometimes even from China. But considering they seem think QC is just a sticker, it's one big lottery (with some very expensive tickets).

I wonder if they made a fat beam on purpose to match combined red and blues?

So what is the difference between the new Kvant models and the existing Laserwave ones? I've heard rumours of many failing CNI units (mainly I think through them being overdriven re-labelled units from 3rd parties) but I wasn't aware Laserwave greens were anything other than reliable so what is the difference contained in the new units? My apologies if this is a dumb question btu I'm not that technically up on laser sheet specs.

The beam on the green in my Kvant Spectrum is the fatest beam in the box. The 445 and 640 are much smaller. The green in mine is a Viasho, although it is having modulation issues and Kvant has requested I ship the projector back so they can install a new green that has a bigger driver; they need to rebuild the bottom of the projector to make it fit. I am wondering if it is this unit or a new Viasho unit.

TBH in the time that I've been paying attention to lasers on the internet I've heard very little about failed CNIs, Laser-wave or Viasho lasers. The most common name that I've seen associated with failed lasers is Lasever and New Star Lasers, but I must state that I haven't really ever looked with the intention of comparing reported failures between brands, so I'm referring only to what I remember reading.
