Combining green

Yeah, you could do that, but then the output will not be linear because the diode voltage is not linear. Right?

I believe these are TTL anyway ...

By the time you have bought the PBS cube and mounts, it might be cheaper to sell those 2 lasers and buy a bigger one.

i have a 150mw ebaser that i like.. its easy to focus and never had an issue with it at all...

One thing no one mentioned about using one driver for both, is the following:

If you are running them in series (back to back) then you have to make sure the current setting for one is a good setting for the other one... and also that the driver can supply enough voltage to run both in series.

If you are running them in parallel (side by side) then the current will be split up amongst the two using the current control resistors as keeperx mentioned. Although, if one dies and results in an open circuit, where will the now extra current going to flow? Guess what will happen to the 'good' one...

I'd say one driver per diode, and you can run the modulation to both simultaneously... my $0.02

You have a great point there. Remember my PM..
