Yob 650nm Aurora C6 260mW

[elite ares]

Recently I acquired a yob built 650nm, 260mW, Aurora C6. It's powered by 2 CR123A Li-Ion rechargeable batteries. It is typical yobresal quality. Power output as measured on my LaserBee II with a pair of Juice brand CR123A batteries is 260mW with the supplied acrylic lens. Running on one UltraFire 18650 Li-Ion 3000mAh battery, output is a meager 117mW. I believe it will run a very long time on that battery without overheating. In the future I plan on getting a glass lens to see what difference it makes. Overall, I'm very happy with this build.

Here is a beamshot in the misty fog. The beam is dimly visible at night without fog but you have to be very close to see it.

Here is a plot from the LaserBee II. Average power is actually higher, I started the plot before I turned on the laser and stopped it when the thermopile reached zero.

I can post the 18650 plot if you're interested.

EDIT: another plot with a different battery

With an UltraFire 18650 3000mAh battery, lower output but gaining power as time goes on. I suspect it would run cool and for a very long time with this battery.

Another beamshot, no mist or fog tonight. Beam visible as well as dot on the tower.

That's one of the best "red" beam shots I've seen!

What diode is it using?

What diode is it using?

The diode is a LCC.

Very nice red laser. I have made my own red laser, also using LCC, Aurora C6 host and 18650 battery but with a flexdrive. Can you measure the current output at the tailcap ? Mine is running now at 200mA and I want to know how much current is needed for 117mW power. Use a freshly charge 18650 if your can.

It is pulling 240mA at the tailcap with a fully charged UltraFire 18650 3000mAh battery at 4.23V.
