I was recently lucky enough to acquire one of the green labbies which Matt ( Mohrenberg) got from ebay. There are no part numbers on it and Matt assures me that is was originally from O-like --- No power ratings known.
Specs:
Laser head: 1.8" wide x 1.18" high x 3.42" long including fan
Pwr.Supply: 2.0" wide x 1.83" high x 4.34" long Much of this is heatsink
Input power: 130 VAC - 60 Hz
Modulation Port: TTL
The 12" cable between the PS and head has 8 large wires indicating that the head is likely TEC cooled. The power supply has two exposed 10 turn pots which I have not tried yet but I'm assuming control LD current and TEC setting. The Modulation port is a minature two pin plug and from testing is TTL as there appears to be no analog slope.
The laser powers up and stabilizes at ~150 mW after 20 seconds. I went to get a power measurement head and when I came back, a screwdriver handle was smoking!! Yes it has power.
This is all I know so far - I haven't measured divergence because weather here is getting bad :-( but the beam looks tight.
