Help me get started!!

Hi!

I got today my laser diode, axiz module and driver.

Diode is PHR-803T HD diode 405nm
Driver is Surface Mount FULL RANGE ADJUSTABLE Laser Driver bought from stonetek.

Im total newbie with DIY laser pointers.
So what voltage i should use and how to setup my driver correctly? I dont want to burn up my only diode.

Thanks already.

 

[Tech_Junkie]

100mW for burning, and longevity. Never over 120mW.

Check the links in my sig for your other answers.

Good luck.

^ What TJ said! You'll get it in no time.

P.s. Nice new Sig TJ! I would rep for that it still won't let me...

 

[Tech_Junkie]

I dont need the points bro, no worries. Thank you for making a thread for the n00bs.

100mA is fine for PHR diodes.

You dont have to set the voltage, you have to set the current, the voltage is dropped across the diode.

 

[zxiicci]

Okey. How do i set right current?

 

[AUTO XX]

you need a dummy load and a multi meter
read about loads/linear drivers here Laser driver - It can be done
I know you don't need the driver but it will give you a better idea of how everything works together

 

[Rafa]

As auto xx said, you have to measure the voltage across the resistor, use 6 diodes, you can get them very cheap at any electronics store. A safe value for PHR's is 0.1V across the resistor, that means 100mA.

Hope you don't kill the diode!

BTW if they don't have 1N4001 you can use 1N400X where X a number, 1 to 7.
If they don't have any of these, well, that store sucks a lot! :crackup:
