I need a very cheap high current driver

[Gofilord]

Hello,
1. I have a DVD burner 48X diode. I'v already built a 20X red and I'v putted 340mA's to it. This time, 'cause it's a 48X diode, does it mean I can put higher current to it, such as 600-700mA?

2. If so, then I need a nice little driver board that can reach 700mA and is under 10$, sorry about the low price.

P.S, this laser will not be portable so the driver doesn't have to be a boost\buck driver.

Can I get more details? a link?

 

[midias]

Laser driver - It can be done

 

[Gofilord]

Great but what about the first question?
because it's 48X I need to get it 650mA?

Not sure what you need to get it to but that driver will do 1.5A

The best red diode is the LPC-815/826 and they max out at 400-500mA. Your 48x diode won't go over it.

 

[Gofilord]

so if I put 500mA to the diode, how much mW will it generate (6V)?

It depends on how efficient your diode is...no one can give you an answer.

would not recommend trying to get a singe red laser over 500mw.
If you do it will have a short life.
Best bet is 2 lasers combined to get around 475-600mw.
all you need is 1 pbs cube 20 -25$ and 2 red lasers. shine them into the cube right and you can combine there power (depending on cube minor losses).

the 48x will be the IR lasers read speed....
