Hello, i want to drive my 10 nm green laser diod,input 4v,output ,2v 393 MA, what suggest diagram for it,thank you

 

hi Zun,
Do you want to pulse the laser diode or continuous,?
I think you have a typo on the 10nm value, typically 532nm.

Yes Continue laser, typo, 10 mw,

hi Z,
Look thru this link for laser Constant Current drivers.
Lets us know which you choose and we can discuss it.

This is a simple circuit.

I just try this circuit, input 4.5 v, just got 280 MA, when input 6.5 v ,I got 400 MA, but this, I need 4.5 v only, for my friend level laser modifications,

How this

 

OSRAM 10mw PLT5 510 515nm Green Laser Diode

The operating voltage on this laser can reach 7 volts (see datasheet). The driver needs a supply voltage of 7.5 - 8 volts. The Chinese make a step-up converter (charge pump) to power the laser driver (for the finished laser modules). There is another system. This is when the current generator is fed by an infrared laser and nonlinear optics convert the IR into a green light. In this case, 3 volts is enough.

I just buy a diod only, true laser diod

For fix to my level laser housing

 

hi Zun,
The laser diode datasheet says operating current typical 60mA, 100mA max at 5.5v to 7v.
I would modify the simple circuit in post #5 to give 60mA at 6.5v

Just thought I'd mention in passing that green lasers are more dangerous to your eyes than red ones.
