6x SF-AW210 What mA for the red diode?

blrock · Sep 18, 2010

Hi All,

I'm giving the big gun lasers a rest today and decided to play with some low power diodes from my junk box. Mmmm, time to strip the SF-AW210 and remove the diodes.

I've search LPF and there is much info on the 405nm laser from the SF-AW210.

However, I'm trying to find out how much mA I can drive the red 660nm laser from this sled. I currently have it set to 200mA. Fairly bright.

Can I drive it some more...

Thanks!!!!!

It is open can, closed can... give a little info on the diode.

I found some info on the second resulto on googles when you search SF-AW210:

The optical pickups also contains many potentially useful optics In addition to the 405nm diode, the SF-AW210 (6X) sleds have a 16X red diode in them. This red diode is a LONG CLOSED CAN diode. They are very similar to the LONG OPEN CAN red diode that we get from the LPC sleds. this LONG CLOSED CAN red diode is capable putting out 250mW + at 500mA!

It is an open can......500mA??? wow thx!!

I wont personally push it to 500mA.... I won't even pass 400mA

If its a long open can or LOC I believe 420 ma is the average current people use you can check here look for lpc-815

As Rafa said they are Long Closed Cans (LCC) diodes like the one in the GGW sled (on right), they can take more current than the LOCs. It will do 500mA easy.

The SF-AW210 sled has a Short Open-Can red.
This diode is not capable of sustaining as much power as a Long Open-Can or a Long Closed-Can (LOC and LCC are basically the same).

Even the LOC and LCCs are unreliable above 450mA. 500mA is NOT considered a "safe" current for LOC or LCC diodes. Some die at this current.

Run the SOC below 350mA and it will live a good life.

I found several websites stating LCC ... I guess they are wrong huh? :/

Never heard of it.

I know the GGW-H20L 6X sleds have the LCC, but I am positive that the SF-AW210 6X sled has the SOC.

Regardless, which diode it is can be determined by a photo. A macro of the die would be great. At the very least some detailed info regarding the diode in question...

Thanks for the help eveyone.

It must be SOC. I ran the diode @ 350mA (as suggested by you guys

) for an extended time last night and all was well. I'm pretty impressed with the little guy. The beam was very visible outside. I'd guess it must be about 200mw.
Sad thing is that I spend huge $$$ on a 500mW 635nm and this "cheap" one is so much better. The divergence is awesome.

Seeing how this was a little while ago that you did this how to death diode laser ever turn out

I think SOC of AW210 cannot handle 400mA+.
When 400mA+, It will die in a few minutes.
