I have two lab units for sale. The first one is a green one that I bought from an ebay seller called Aerospace Dynamics. It has a basic power supply. Once it warms up it stays around 590 with a peak of 640mw. I do not know how to measure divergence but I can tell you that my 473nm lab unit has a better dot. It has some scratches on the head and the supply. The scratches do not affect the performance. When I take this thing outside my brother can see the beam from 3 miles across town. It is a very good burner if you are into that. In my pics you will see that the power cord is spliced, this is how it came. I'm not sure but I think the seller did that because the mains here is different than there.

EDIT: Green is sold!

Blue still available-$350

The second one is a 473nm unit. It has matching serial numbers on the head and power supply; BLM-100 III 7050058. This one stays between 55-58mw, nice and steady. It has a slide shutter on the aperture. I was told that the company that markets these buys the CNI 50mw units and then sells them as 100mw. This one has a very tight beam and a tiny dot with no splash or artifacts. This one is in excellent cosmetic shape! It will be tough to let this one go because it is my favorite laser.

I am hoping for $400 apiece. I will take some off if you buy both. Price negotiable.

I have never posted pics here before but I am going to give it a shot here.
The first two beam shots are without smoke or fog. The last two beamshots have some smoke from three matches.

EDIT: Blue is sold!

What kind of modulation do they each have (analog or TTL)?

Peace,

I metered them myself. I have an Ophir 20C-A used in conjunction with my DMM

is there a way for madog to find out if the units have only TTL modulation or also support analogue modulation?

I've seen the other auctions the guy who sold the green labby has had, they're TTL only if memory serves.

I took the cover off of the power supply but I don't know what I am looking for.
I did not see a switch.
If it would help, I will post that pic also.

Please post maybe someone else can get info from it if it has analog modulation?
But the post above you kills my in-exiting-state:(
