Dual RED Driver questions

Hi all.

I am building my first dual red laser.
I have a Die4drive Driver and using analogue modulation.
My required output current is 350mA on each diode.

I have found some info on here and around the net, But nothing conclusive.

My questions are...

Can I just connect both reds to the same driver output?
Series or Parallel?
Will one pull more than the other and cause problems?

Thanks in advanced.

Depends on the driver though - with linear drivers you can connect them in series, provided they are electrically isolated from eachother, and you have enough supply voltage to run them.

Paralel is also possible, but requires some small balancing resistors in case the diodes dont behave identically.
