Blu-Ray Current

Just wanted to know if anybody else is running their 803T at 100mA. How is it working? Do you think i should turn it down?

100mA is fine.

Peace,

I'll take your word for it
I have a good heatsink!

As long as you dont hit 101mA you should be alright. If you do, it may create a small black hole that could devour the earth.

Oh no!!!

I don't think 1mA will make a difference...

Been running mine for the past week at 100ma, no issues. No heat sink to speak of, just the Aixis housing it's pressed into. I never run it for more than 2mins at a time though.

Yup ;D

GGus -- I think he went over 100 mA The earth beneith my feet is getting thin OMG a black hole --- Oh NOOOOOOOOOOO ---

Quick!!! Turn the pot!! TURN THE POT!!! ;D

just out of curiosity... what is the "consensus" here as to what is considered the highest safe current on the 803T BR diode that won't kill it realfast?

Let me be specific - say I am heatsinked in an Aixiz module fairly well - how much can I feed it for say 1 to 2 minutes at a time with a minute to two minute rest period between cycles without killing the diode in say 4 seconds?

I'll be blunt. I was curious like everyone else is... and I started farting around with the pot... not realizing how fast that son-a-gun ramped up the current. I saw a very impressive beam for oh... about 4 seconds. :
and well.... I have a couple more diodes here... and the itch to crank up the juice on it with a dummy load this time (yea I know, I know. Idiot. I know I should never have touched the pot with the diode attached... call it a momentary lapse of sanity) and see what a powerful beam looks like in-person.

So... given the case above, what have you personally have first hand experience with current-wise on that particular diode? I am looking for normal here, not "freak cases" to be more specific. So far I have not had the cajones to go over 94mA with it... but now, I'd do a 100, maybe a hundy-five now no worries - but realistically speaking - how much further have people taken them and had them last more than a day?

What you are doing is exactly how we find out. Kill a few more. Write down everything you do. Let us know what you discover.

Peace,

Oh.... I see.... that's what I was afraid of ;D

This is where science happens. Read what we have done -- Do your tests and post your results. I have many dead LD's from my testing -- Some cost over $300. Go for the gold ;D You will get little thanks but personal gratification -- Priceless ;D

Here is the deal - I have two more sitting here, I am willing to give one up for the team ;D I'll start it at 100mA and run it for a minute, two minutes at a time... and see if it lasts for say 20 cycles of that. If it does, we'll take it to 110 - do the same cycles, and again at 115mA since that is what climback showed a mW rating for in the table of Dr. Lava's post in the main thread. We'll take that one a little further and go 30 cycles with it. If it lives, what do you think we should go? 5mA increments to say 120, and then 1 mA increments after that? Or has the 120 mark been breached a few time already?

Let's make my sacrifice useful... we have until whenever to design the experiment in order to learn something from this. If we have any other kamakazi renegade diode wreckers out here that want to take one for the team, let's establish a legit testing criteria so we can have apples-to-apples comparisons of results. I mean, we hae to make it realistic and fairly easy - I think most of us that would be willing to make a $20 sacrifice for the sheer experience of it would take the time to do it with at least some repeatability.... so what should we say is a good duty-rest cycle for this experiment? I don't know enough about the charistics of these things to say the cycles I mention above are any more useful as say running only 3 sets of 2 minutes on, 1 off. Heck, even a one minute cycle? :-?

Let's doe a D.O.E. here and I'll kill it in a few days. Maybe if I get border, I will order up another one. I have a decent job. I can take the occasional hit ;D... as long as it's for science

Better yet - if someone (hint: maybe climback ;D ) was interested in running this experiment that has access to a lab that say... had a laser power meter... we could get even MORE useful data by adding the observed output power in mW to the table.

I'd be willing to mail it, If someone with the equipment would be willing to scientifically run whatever D.O.E. we figure is useful. I don't mind buying a few if we can learn something here.

PM whoever you think is a useful candidate with this thread and have them contact me. Let's do some 'xsperemintin' here

Oh, and for the sake of cheap postage, let's make me only send this out in the US. I can mail it here for less than a buck.
