8W RGB and New Modules. New Company: AtenLaser

.....The primary problem are the coated facettings of the chip (the resonator). These can´t handle this power in showuse very long, even not 1W instead of 700mW. ......We tested the 700mW diodes to (as all other on the market avaiable SM and MM diodes which are usuable for showuse) and got different results........Phillip

Interesting " facet coatings" observation here ......Any chance of you sharing the results of those tests
I am curious ... how did you measure/detect this facet coating degeneration? and even more interesting is how you were able to rule out temperature as a possible cause !

Sorry Jordi, might be going a bit off topic here,... but I think quite a few lurkers here would be interested in Phillips reply!

Cheers
PS. @ Lasermad.....BCN selem is a great idea....but P, didn't know you worked for Easy-Ryan !

Hi!
Just post a pic of what we working with for the tests.
The temperature stability caused by a fullbridge tec driver and a easy mount...
You can measure the loss of the facetting by using a beamanalyzer and making a raymeasurement on different time settings.
You will see how the beamshape is going bader and bader, the power losses while the facetting getting burned.

Perhaps you should post your results of these tests Phil - if you want us to believe this is anything other than competition and sour grapes....

Can you post this data? I am very interested in the relationship of drive current to life time. Also, It would be interesting to know the COD point of some of the diodes we use.

It would be very beneficial to know if we drive these diodes at X current the life will be reduced by X time.

When the P73 is driven at 50hz 33% duty cycle at 1 watt peak (330mW ave) the life is 13K hours. This is the only data mistu will give. What if the freq was pushed to 5Khz?

Hi Phil,.... think you must have posted mistaken pic ...even if you used a spectrometer in the tests ...pic shows nothing useful!
Maybe you went out on a limb here, dunno!..... but this "facet degeneration" allegation has "got me knickers in a twist."
@Dave ......."sour grapes.... "...... this isn't sour grapes Dave IMHO ... it's a frigging slow fuse atom bomb!
If slightly over driving, a temp coddled, air conditioned, Mitsu is carcinogenic ! .... most of us have a wee problem under our bonnets!
Sorry 4 temporary thread hijack Jordi, ......... but this is extremely important to just about everyone on PL who uses P73's/Oclaros
Cheers
PS. If this issue drags on too long, maybe better someone starts new thread, "Doubts about Red MM diodes"

[catalanjo]

Sorry about the hijack folks
The trouble makers will leave the building ....along with me and Elvis!
Dave,Woody,Phil ..... get your arses out of here ....this is a propa laser pornography thread....not for Gentleladies !
Now you can all get back to "drooling" if Jordi post a few more pics, with near & farfield measurements of his new baby!
Cheers
