Sorry to post on an old thread. But, why do you need a driver. If I make a laser from a mini mag and an old dvd burner do I need a driver or can I just solder wires direct to the diode?

I'mg answering this just because it'll come up in the future if someone (unlike yourself) uses the forum search to find the answer.
Simple answer:
Laser diodes are current driven devices. Batteries are voltage sources. To convert from voltage source to current source you need a driver.

damn thats an amazing diode and color for sure. how much does something like that cost?
Here is an estimate :eg:
Thorlabs - L488P060MLD 488 nm, 60 mW, Ø5.6 mm, B Pin Code, Laser Diode w/ S05LM9 Mount

Would setting the power to 24ma brought it down to about 4.9mw? Or is it exponential? I'm trying to get down to a safe level blue build. No one seems to have any build info for a safe level blue. I have scoured the boards looking for a Safe blue build.
Priorities. First, where did you get your 488nm diode?
I was asking a question to learn. I do not have a 488nm diode. However if I chose to purchase another diode 445nm, 450nm, 473nm, it should have a similar chart on it should it not?
Nope, not necessarily. In fact, not even likely. Even within the same wavelength, different models have dramatically different curves. Here, you've replied to a thread about a wavelength and diode that is exceedingly rare, and very experimental. It's specs are irrelevant to your challenge (unless you're willing to shell out the several thousands of dollars that this specific diode costs).
You may have some luck posting in a thread about one of the lower power single mode 450s.
