really what i want help with is what diode can i buy to replace the one i was trying to extract from the dvd burner. Has to be under $15 because i don't think i it is worth spending more on a project like this.

look guys I'm sorry i am just an amateur at all this laser stuff. 1. i built a constant current driver. 2. because the driver i built was supposed to be cheap not efficient a lot of the power going though it gets turned to heat that is why I'm using a power supply instead of batteries. i...

i modified a compute power supply

sorry i didn't fit your criteria to answer my question. i was going to use a diode i pulled out of a dvd burner but it broke in the extraction process. i want to know what mw i need in order to make it a burning laser. using 87 octane can of gas

hey guys can anyone suggest a good laser diode for my computer power supply burning laser project. it puts out about 6 volts. anything helps i don't know a lot about lasers.
