Trying to find right transistors to use for a project...sal2

Greetings, All

I would like to switch on and off 4 of my 4mW pen lasers on and off (in various ways) using my usb 6008 DAQ device however I don't have enough current/voltage to power my 4mW pen lasers from my usb-6008 DAQ device. Here are some Specs that I've measured from my device. The digital outputs on the DAQ device produce:

What I would like to do is connect my 4 digital outputs from my DAQ device to

I'm having issues trying to figure out which Transistors I need. Can anyone give a little assistance.

Also if you have any other suggestions I'm open to that also. I'm allways willing to learn something new.

Note:(DAQ) is short for Data Aquisition)

Thanks sal2
