Got a DVD laser!

[450nm]

Wow! This is G-O-O-D!! I got a knackered 'Benq' DVD writer and dropped the laser block out. The diodes are 'typical' 3 pin jobs. I am feeding the red one with 160 mA and it is almighty bright. (I've been playing with 5 mW ones).

2 questions.

1:- Does anyone recognise this block and can gues at what is the maximum current I can safely put through it to play with in CW mode?

2:- How do I go about collimating the light to give me a beam.

Sorry if the questions are a bit basic but as I keep saying, I'm very new to lasers.

Thanks for help - Dave (A picture of the block is attached)
