^^ Soo what are we supposed to do with that..? BTW your "circuit" has no power source.
I guess I was expecting something along the lines of the circuit path of the driver, this just shows driver switch and diode wired up. Reminds me of a simple science project in 2nd grade

wow that diagram is horrible. and there is no difference between either the left or right drawings....

It should just show you how i want it the "battery" is the current source and the switch should be after the driver and not before it. The drivers are in the modules that i want to use included ,just the driver for the 635nm diode is a LM317 driver with 2 capacitors i will upload another circuit for the driver of the 635nm diode .

No, no, NO. (insert generic gif here.)
Your switch goes BEFORE the driver, otherwise it's gonna get a nice charge, and then when you turn it on, boom goes the LD. At this point you'd be 100x better off buying a laser that is already put together, you clearly haven't done enough research yet

I won't buy a already put together module i want diy and the only circuit that i can show you will be the driver for the 635nm diode its a simple LM317 driver with 2 capacitors

No the resistors are used too but the standard LM317 circuit from styropyro don't uses capacitors so i added capacitors i mean it so ,current loads the capacitors and when current drops or gets higher for a short Time the capacitors are Balance that change so that there is nearly no risk of killing the diode .

The LM317 is all you need. Capacitors do nothing more than serve as sources of charge that can accidentally fry your diodes. Most caps are added to LM317 circuits just to remove ripple or other sources of noise, not as a means to protect circuitry from current surges or ESD. You may have to add additional protection diodes to prevent the extra capacitors from negatively impacting the circuit. I would leave them out.
