635 nM diode

[Hemlock_Mike]

I received my DL-6353TL laser diodes today (ebay)..
They are rated for 7 mW of 635 nM output with a 40 mA max current.
After mounting one in an Aixiz module, I proceded to light it up with a current range of 20 to 60 mA. It appears that current over 45 ma (11.5 mW) is at the knee of the curve but I did achieve 14.9 MW at 60 mA. (No, I didn't burn it out --- yet ;D)
Diode voltage is 2.27 volts at 45 mA. The beam looks red until you put a 660 nM beside it, Then it looks like a HeNe beam.
The picture here shows a 660 - left and the 635 - right running at 4 mW. It's hard to see the difference through the camera.
NO - - It won't burn, light or cut stuff -- Don't ask.

If I didn't know I would have picked the one on the right.. ;D Like you said the difference is there but barely noticeable.

 

[Hemlock_Mike]

Your eye can see the difference side by side.  Oh, those two dark spots are burn spots on the target from previous experiments !

Mike

Another picture -- 660 --- 635 --- HeNe (the poor old HeNe only outputs .63 mW )

Actually I do see a good difference between them.The 635 is orange-y-er while the 650 is way more cranberryer

 

[wooooooolazer]

to bad the high powered 635, like ones as powerful as dvd burners are multi-mode, and if there were some single one im sure youd have to dig in your lifesavings to get it.

...lzer... ;D ;D ;D

I built a 635 diode into a small flashlight (1 aa Cell) today. The flashlight is an
unmarked clone from DX. OK quality and I should have used it for a 405 because the boost puts out 5.6 volts !!
Anyhoo, It puts 42 mA to the diode now and I read peak 12.8 mW of 635 nM.
The beam in dark is slightly visable.
The only problem I had is that the diode is case + I had to isolate the module but 2.28 volts at 44 mA ain't much.

Could we get more info about that flashlight host and boost circuit please ? building a bluray soon.

 

[Hemlock_Mike]

Darn -- It's a basic, unmarked, painted, cheap copy of an Ultrafire. I got it last summer and wasn't impressed with it so I made it into a 635 !! DX may not even have it anymore. I'll look.

[Hemlock_Mike]

Go to DX and look under Flashlights, other. The SKU 2070 and 5383 are similar to mine and under $5 !! I don't know about the driver.

Ok thanks

 

[Hemlock_Mike]

Paper, I found another in my pile -- still in the box --

Marked 2070 -- 1 Watt

Okay, do you think that could be a host for a bluray without any or minor modifications to the booster circuit ?

 

[wooooooolazer]

it sounds like it would be perfect since that is right around the voltage and ma it takes, the voltage might just be a little to high but a smalll resistor should fix that, and a cap couldnt hurt.

...lazer... ;D ;D ;D

 

[Hemlock_Mike]

Let's keep it simple like my Blu I measured the output of the boost at about 40 mA. I had the volts !! I added resistors (and the needed cap) to drive the diode. If the boost holds steady output -- you have a CV driver with a resistor limiting the mA. KISS !!!!

ive i ever build a blu-ray i got to try that, and those flaslights are sooo cheap.

...lazer.. ;D ;D ;D

 

[jamilm9]

i ordered 5 of them for my blu-ray.
