I have recently decided that i want to build a laser pointer and have been looking around for some (mainly a decent diode as other parts are more common), I came across a few high power diodes on ebay being 1.4-1.6W but I have a few questions about the construction of the laser.
As mentioned i found a few diodes that are 1.4W and I couldn't work out how much power would be required to power such a diode and whether the driver and module I had found would be suitable for it.
Your help will be much appreciated and I would like to further ask for suggestions on parts to build a laser, I would like the output to be around 800mw but higher is fine however I only have a budget of around 30-40 GBP so I am looking for something cheap that will have a decently visible laser and have the ability to etch plastic or light a match.
Thanks in advance,
Jake
