I am looking for a driver circuit for a laser diode Answered

this is the diode I am talking about http://za.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6541866

I am looking for a circuit to build myself so if any body know of a place to find such info it would be greatly appreciated

Are you wanting to modulate the laser ? - If you just want to power the diode up to create a non-modulated beam, you can simply power it from two penlight batteries, with a current-limiting resistor in series. I did this and created a nice laser pointer in the body of a pocket torch.....replacing the bulb with the diode.

Hie thanks for the reply I actually knew about that instructable but I weren't sure if that circuit would be compatible with my diode would that one work?
