Pictures of a 780nm laser build

Blord · 12-12-2011, 11:30 AM

Hi all

I had some 780nm diodes left over from harvested sleds and have decided to build a 780nm laser.
My DX Dilda red laser has short-circuit inside and burnt the driver and the red diode. So I use this host for the build.
All the components are removed from the pcb and I use the LM317T for the new driver. The current was set op 224mA by a 5.5Ohm resistor. I didn't want to heat up the 1/4Watt resistor too much.

The famous Dilda laser

Flexdrive and Jib driver to compare the original driver.

Plenty of room to use the LM317 ic. It was place on a sticky heatpad.

The burn mark from the short-circuit is still there.

Ready to lase

A tiny red spot burning the paper. A very small smoke is seen

I hope you like it and be carefull with the invisible 780nm laser.

Yeah cool wanna buy a nice host with lens assebely ?

<--- click for big

No thanks, I will stick with my C6 host

making your self seem desperate to sell that host lol.

It's just for sell

Wow, nice laser! It's invisible, which makes it so much cooler. ^.^

How much power does it have? Nice (semi-)build!

Blord · 12-31-2012, 10:51 PM

It has 160mW output measured with the Ophir LPM.
That was a long time ago I have build that 780nm laser. I have another 780nm diode in the C6 host. I don't use much of them. The dot and beam are invisible and the burning isn't impressive.
But I build it for my wavelength collection.

Sorry for posting here, I only saw the post's date just above me! Happy new year!

Interesting build Blord. Just another to add to the list aye!

get some night vision on it!
