Google this "simple on off ir link", tons of DIY projects....

Off the shelf, one of several,

Your question is way too broad. It has so little information that there are dozens of ways to do what you want, or hundreds of pre-assembled modules to choose from.

What is it that you are trying to achieve?

What power sources are available for the transmitter and receiver?

What is the maximum range you need to cover?

Do you want to design and build circuits from scratch, or buy modules and wire them together?

Does anyone know how you would build this?

Yes.

 

[Nooboob]

Yes.

Care to elaborate

I think I misspoke, I'm looking for a device that transmits an IR laser with the ON command so when a receiver comes in contact with it it turns that device on

 

[AnalogKid]

Much better.

Does it have to be a laser, or can it be a narrow-beam LED?

Range?

Power?

Do you already have the receiver?

You first.

In terms of designing or recommending a solution, your question has almost zero useful information. His answer was an attempt to make that point.

You're still telling us nothing helpful.

I think that this thread might be an example of the XY problem.

Also known as debugging their solution not their problem.

Here is a quite simple tutorial. I hope it will help you. This circuit consists of a 555 timer and an IR sensor.

Circuit Diagram of IR Sensor using 555 Timer - The Engineering Projects

Today's tutorial is quite simple and we will have a look at circuit diagram of IR sensor using 555 Timer. There are different types of IR sensors ...

Another key question is:

The "Receiver" - is that something you want to build to for this job - or is is an existing device that has an IR remote control??
