The amazing 322mW Dilda

Hey guys,
did you know...
the last DX200 I bought had an output of only 147mW when it was received.. (one of the
weakest ones... I have 5) and did you know... that if you increase the voltage to the
"regulator board" it will not regulate the laser diode's voltage or current but it will
increase the output power of said diode...

I just did a test up to 8 Volts regulated and got 257mW...

I shut it down right after it hit that number... I was afraid it would explode
in my face...

The Dilda's output seems to be input voltage dependent....
When I get up the courage... I'll probably try for 275 or maybe 300mW..
My only concern is the regulator board... even with 2 CR2s (6V) it heated up
quite a bit.


EDIT

Holy Crap... I just did another test on the Dilda... I took it slowly up to 12 Volts
regulated and the dang thing put out 322mW

That's a $43.00 200mW rated Red Laser.. that most people shoot down b/c it doesn't
do 200mW out of the box.

If I get the nerve up... maybe tomorrow I'll see where it levels off...or dies...

the drivers definitely aren't the best, but it's amazing that it didn't die or have the driver burst into flames at that voltage ;D

I can't believe that thing hasn't fried yet. Even if it does fry, it will make a great host for an open can or even a 6x/803T.

Yeah... that's what I was Thinking...  :cool:
Don't for get I only left it at those powers for 5-10  seconds... :-/
Too scared to leave it on longer... :eek:

Well... tomorrow it's the big test to (hopefully not) destruction. ;D ;D ;D

The dilda uses long closed can diodes, they are like pong open cans, but they have a can. ;D

Is there much difference in power VS current between them ?

There hasn't really been any testing on the dilda diode itself, but my guess is that it is like the phazor diodes from that one GB a while ago, which died at around 320mW CW IIRC.

Can you remember how long they were run at these powers? if they can be run safely with a 1 minute duty cycle that could be interesting .

I just peaked out my regulated Power Supply... The dilda still put out
322mW and was pulling 650ma at 12volts...  :eek: That's 7.8 Watts of Electrical Power
I left it on for 20 seconds.. output dropped to 320mW.  :-/

holy crap what type of diode is in the dilda cause i built a 16x red burner at 300 ma and it wont even come close to either of my dildas those things burn like a mad-man !!!!!!!!!!!!

2mW drop is probably due to heat :-/ that things pumping out 7.47W of heat :-/

They don't manufacture it.

And using a better heatsink would mean using copper, which is heavier and more expensive, or making the current heatsink bigger, although if they made the laser bigger so that it could fit CR123s that would also increase the heatsink size and improve the laser.
