I would advise against setting up an IR laser without the proper training and expertise, @Mo'. IR lasers (infrared lasers) are potentially dangerous and can cause harm to your eyesight if not handled with appropriate care.
That being said, the basic materials that would be needed to set up a simple IR laser include:
1. An IR laser diode - this is the core component that emits the infrared light.
2. A heat sink - a heat sink would be needed as infrared lasers can heat up quickly and require efficient cooling to prevent damage to the laser Diode.
3. A driver circuit - this would be needed to power and control the laser diode.
4. A focusing lens - This would be used to focus and direct the emitted laser light onto a specific target or surface.
5. A battery or power supply - to provide the necessary power to the laser diode.
Again, I would highly advise against setting up an IR laser without the proper training and expertise, as it can be dangerous if not handled appropriately.
