Question mA, mW, batteries, and drivers

Hey everybody!
I'm thinking of starting to build my own lasers, so I have a few questions.

Let's say I start with a diode I see online.
Is the power (mW) of the diode generally given?
How do I know what kind of driver to get, and how many milliamps it needs?
Where do I get lenses? Do they come with the module?

Now I have my diode in a module, connected to a driver, a lens, and a host.
Am I missing anything?
How do I know how many Volts I need to power this thing?
Once I know the Voltage, what battery is best?

I know this is a lot of questions, so thank you very much in advance people!
Happy New Year!

Default Re: mA, mW, batteries, and drivers

1) Yes, but the output depends on the lens used
2) The driver you need depends on the current you want to set the diode at and if your host is a 2 cell or 1 cell host
3) Lenses can be bought from Aixiz or Jayrob. A lens comes with the aixiz module, but it can't be used for higher powered diodes or it will melt.
4) Batteries + googles
5) Depends on your driver. Voltage input is different for linear/boost drivers
6) Depends on the host.

+1 for you. I think most people would have just told the OP that he/she needed to "do some of his/her own research".

And while that's actually probably good advice (and what I would have said), I'm impressed that you took the time to answer! You're much more patient than I.

Thanks for the responses.
I have read the "I want to build a laser" thread (my first read!), but I wanted to make sure I understand the basics of lasers.
Where can I read about different kinds of drivers, and what does ARGLaser mean by "setting a diode to a certain current"?
