laser driver

Archiver

I have a laser pointer but the driver doesnt work.

I would like to know if anyone have a diagram or knows
how to build a driver for a laser pointer, I just know
that I need to generate a high frequency.

Thanks for your help
Alex

Alex,

This is the best reference I've seen on the web:

Alex,
If you only want to drive a small diode try your local electronics store
The sometimes sell laser pointers as a kit
The PCB containing the Laser Diode and driver is usally quiet small
