mini laser driver for 1 w blue laser pointer? Answered

Hi anyone here?

 I need help with the construction of mini (using smd)  for 1 watt blue laser driver.
I find it difficult to obtain the circuit for the driver. I would be grateful if anyone can help me.

Thanks in advance.

You need a good, clean, constant current source, ideally.

What input volts have you got ?

Thank you steveastrouk for you initiative to provide me an answer. I can get any voltage at 1 amp.

But without a circuit I cannot begin to construct a driver ( SMD mounted circuit)
Anyone like to share the circuit (double sided ) circuit board for the mini driver.

Thanks in advance

if you're OK for volts, this circuit is about as minimalist as it gets ! Note the resistor needed: 1.22/ current in AMPS
