Start of the 3watt RGB

[tocket]

Hi Tocket,
I promise, all of laserwave's products are using lower current than supplier marked used current.
we know there is not only power, but also lifetime, it is also very important.
Just as I said, much improvement than before unit, trust me, mate,after ourself strictly test, maybe we'd like who with well reputation interesting test this unit for all of us, .
Best regards!

Yes, I know... what I meant was that they are tuned in CW mode and very few of us use them like that. I have no doubt that Laserwave lasers are of very good quality and built to last. However, we use modulation, which means it's not running at full power all the time. With DPSS lasers this has many implications. I don't know how to adapt the driver settings for this, but at the very least I feel the power should be the same in CW mode as in analog modulation mode with 5V potential between the pins (mine isn't). I suspect there are many more modifications you can do to improve modulation.

As for testing the unit, I think drlava has a very nice setup for testing modulation. I would in fact be very interested in reading such a review and it would definitely be used as a reference for any future laser purchases and recommendations.

its not a problem at all, makes to odds beam wise, but it would just look better a few inches in

Hi Tocket,
our laser can do CW, TTL, Analogue with switch below the PCB board.
yes, Analogue input voltage change from 0-5V, power change from 0-max, that is the truth.
sorry for I am not very clearly understanding your meaning, but sure is 5V input, max out put power for analogue.
before our shipping, every lasers will do Analogue test here, "P1t8ull" "uncleworm" ......here know that exactly, they had did the compare with others before,.
thanks for your advise, any reply is welcome, that is supervise us do better and better, .
best regards!

The offer to test still stands for Bridge
I too want to start this standard of testing for laser modules, especially DPSS which can be sensitive to these tests.

How about one of your new style, Bridge?

Hi Tocket,

I think what he meant Bridge is that very few lasers put out the same maximum power in analogue mode when modulated at the full 5 volts as they do when used in TTL continuous wave mode.

Maybe Tocket could confirm this.

I think Tocket is referring to what I called the duty cycle dependency problem.

This vid shows it well:

Look at the top left figure, its color varies from orange-yellow to green-yellow when going from low duty cycle on the green to a high duty cycle of the green.

CNI fixed this problem for me on that laser.
I also had to tell them that I wasn't interested in more output but better modulation characteristics.
For RGB application this issue needs to be resolved.

Bridge, I hope this helps understanding the issue, otherwise PM me.

@zoof

That's is one big M.F. of a baseplate you've got there, Matthijs.

Others could learn a lesson from that.

LOL, it weighs 12kg just to make sure the optics aren't going anywhere
Cooling hasn't been a problem either

I found it in my parents' basement, it is surplus from a Carl Zeiss lab. Not sure what the original instrument did.

Hey Zoof,

Nice pics of your RGB set-up. I'm going to be building an all solid state rig soon just for portability sake. Argons are great but BIG.

Regarding these wholes, it would make more scene to put them the other way, then you would get adjustment in the required direction. Moving a laser back and forth doesnt help much when alinging.
I know this would mean the base plate would have to be wider, but it would save the customer drilling elongated wholes them selves.
