M140-445 TESTED laser diodes FS:

OK now we have tested M140-445 laser diodes for sale.
These diodes have been tested to 700ma on a calibrated
lab supply to be sure there are no dead ones.
You will be given the voltage and power out @ 700ma input,
with this info you can tell just how efficient your diode is ;)
They have not been tested for any other parameter.
They are $37.00.00 each plus shipping and PP fees.
This is not a GB they are in stock and ready for shipment.
They will be sent with a shorting jumper to keep them safe ;)
Pressed into an Aixiz module add $5.00
Pressed into an Aixiz module with silicone leads attached
add $7.00

Yeah, the shorting jumper is a good idea for shipment. I haven't lost any LD's to static yet, but there's always a first time. Killed alot of phr's in the past. :)

I'd like to pick up one or two of these....for the PP fees do I just figure 3% or the total and add it?
Thanks
 
I'm glad you brought up the subject of PP fees as it seems there are many
people that think they are 3% stright across the board.
I even just had one member yesterday calling me a scammer because his
figures didn't match mine !
can you emagine that being called a scammer over $3.00 on a $395.00 order :crackup:
This is how it works out for me any way check your figures maby your
milege is different than mine.

recieved--------Fee
$10------------$.59
$15------------$.74
$24------------$1.00
$60------------$2.64
$110-----------$4.59
$210-----------$6.39

So check me and tell me if I'm wrong but dosn't is change depending on how
much money changes hands, it would seem to me that it goes from 5.9% to 3.04% in my case.

So to answer your question about if you should add it or what, I will PM you with that info, Thanks ;)

Peace All...

I am interested in trying holography with this diode running at 200ma.
Any way to test your stock for stability at low current? (cherry pick =p )
 
They're unstable around 200mA. I would run 250mA-300mA at the lowest for a 100% stable beam.
 
Sorry I do not cherry pick the diodes I only test them to be sure they are
not going to die @ 700ma and I will tell you what yours puts out @ 700ma.
but that is as far as I test them !

Why do you only want it to run at 200ma ? these diodes need at least 300ma
and 350-400 will make them more stable if your looking for less power use a
couple filters and turn down the optical output.
Have a good day ;)

Holography really requires single mode. Some people are trying to run these low enough to only have one emitter lasing.

Peace,
dave
 
I know nothing about Holography except sometimes people make some realy cool pic's ;)

Don't bother, these things are multimode right at the threshold. It gets worse with higher current, but its never perfect - even on the treshold you already get a big stripe.
 
In stock and ready to ship "TESTED" A140-445 diodes Guaranteed not to be DOA :D
These diodes have been tested to 700ma on a calibrated lab power supply under
MIL-SPEC ESD procedures to assure that no weak or dead ones will be shipped ;)
Removed the way they should be by a skilled person who has been soldering for 40 years.
Get em now for only $50.00 each.
Please PM for more deatails.

Peace All...
