Wondered what the thoughts were on this, seems very cheap. Ok so its not quite TEM00, they told me its more square like? But 800mW! Beam is big, divergence is not great..... but am tempted.

Analogue modulation is 10khz max. I was also informed of this. What should the min. mod spec be for 30K scanning?

Thanks for any input on this.

I have one of these lasers, the beam is more like a stripe and a very big one at that... After around 6 Mtrs the beam was about 8" x 1"...

I would take pics for you, but the laser is not currently in my possesion...

Also found these at Dragon lasers (CNI distributor): http://www.dragonlasers.com/catalog/...r-p-16329.html slightly better divergence?

By the time you pay duty and postage on Dragonlaser (and duty on the other one) you're getting on for £400+ anyway.

Also, note that if you select analogue modulation on the DL site the price goes up a reasonable amount.
Analogue >10k = ~£450

[gratuitous sales pitch]Might want to take a look at my Laserwave 650nm in the for sale section... [/gratuitous sales pitch]

I would not recomend you buy that snoctony laser if you planing on doing graphic shows. or for that matter run it through a normal galvo mirror as it will shoot outside the mirror if placed only 30centimeters from the galvo.

Here is a picture of it from just 40centimeters. The spot is more like a line-laser and about 1.2Centimeters in lenght.
its quite bright but only at 2-3meter, after that the beam gets so wide it more looks like a red flashlight.

ANd if doing graphics with it you will have to lower your green or any other color to about 80mW to match, as the red beam is so wide it is imposible to make an RGB out of these.

And as you can see its very far from TEM00

I have actually emailed the seller/manufacture this picture and asked them how they can sell these as "Near TEM00" and asked if i can send it back to them and if they can even fix the beam to be litle tighter, wich they answered they couldent.

I bought mine about 2years agoo and it failed to get over 700mW so after a while i sent it back to them and they replaced it (wich was nice) with a new one
and that reached 800mW but after 3min of runtime it goes flipper floppering between 500-780mW nonstop.

Yes its really cheap, so if not to serious about your stuff YES its Cheap. to cheap to be true :P

I will not say its a bad laser, and perhaps other have had better experiance with these lasers, but for me, these lasers are just the ones who makes the words "Bad China Lasers"
a name.

I have not had the nice experiance of buying a laser from Laserwave/Bridge just yet but if you are looking for good prices i would check them out.
Many people on here has bought from them and only good experiance from what ive heard so far.
Not all china laser are "Bad China Lasers".

Sorry to hijack the thread but on the subject of Bridge is he still around?

I've not seen anything from him in a long time and what with the recent earthquakes in China I'm starting to feel a little concerned.

When were they? I was talking to him last weekend ...

[White-Light]

14th April I think the last one.

My last email from him was on the 17th of April.

Thanks, my friends, I am fine, Yes, the earthquake is terrible here, lucky is I lived in Beijing, thanks for attention, my friends.
Sorry for not check PL forums often, because Laserwave is busy prepare enlarge it's product ability, we had passed World while economy crisis, laser marketing is also increasing, that's good news for all of us, right?
back to this threads, we advise you choose small beam red lasers, just like 640nm and 658nm red lasers, 300mW small beam(~3mm, 1mrad) 658nm maybe more brightness than 800mW fat beam 650nm red lasers, consider you loss much after scanner mirror, waste much power as your green and blue is much small than red , most is which make your system look like RGB surrond by red lasers.
Best regards!
