3W 652nm Fiber Coupled Diode

[Laser Ben]

I got a nice new SDL-7470 Fiber coupled diode. It is brand new. This model number was used to pump solid state lasers. It is rated for 3 watts at 652nm at 13.7A. I tested the diode on a spectrometer and it came out to be a little over 652nm at around 658nm, but it seemed to be warm so with a TEC it can easily be gotten below 650nm. The fiber has a nice small core so it can be collimated well. The picture of the beam here is on my wallet at a few feet when collimated with a acromat.

As for cooling, the diode will produce around 25 watts of heat when running at the rated current. You would need to use a medium size TEC to get this to way below the ambient temperature.

What you get:
-Diode with 1 meter detachable fiber
-2 sets of stock connectors for power
-A 3 foot power cable assembly with 14gauge monster cable
-2 Precut Indium Foil Gaskets for heatsinking
-1 Thru-Panel Fiber coupler

I am asking $700 OBO for the diode with international shipping

trade you my Freddy's BMX bike for it?


nah trade you a Coherent laser power meter model 213 with power puck

Ohhhhh Daddy wants! Too bad my laser budget is close to zero right now. Need a Bunch of drivers?
That's a nice diode Ben. What kind of beam specs are you getting with the coupler?

[Laser Ben]

Just want to say that I can't really trade for much now. I can do a partial trade, but not 100% unless it is for something REALLY good. I will PM both of you in a minute.

Is it really a laser diode? Broad emission spectrum and low efficiency makes me doubt it.

I am curious about what kind of beam you would get from it though.

[Laser Ben]

It is a diode, the reason that the emission spectra looks so wide is because it is zoomed way in. When you look at this emission compared to that of an 808nm one, it is just as wide.

I tried to collimate it with a 7mm focal length lens and got a 5mm beam. I do not think it is the best lens for the job. I think a lens with a 4-5mm focal length will works much better with this considering the angle the light comes out of the fiber at.

Diode Has Been Sold! Thank You all who were interested!

Not suprising! Congrats to the lucky winner... we want PICS when you have that beast properly assembled
