Convert infrared radiation into microwave radiation?
Hello, I would like to conduct an experiment to convert infrared laser radiation into microwave radiation. How do I do this? The microwaves should be as monochromatic as possible.

It is possible to convert infrared radiation into microwave radiation by using a suitable transducer or a component which is referred to as infrared microwave converter (IMW). There are different types of IMWs based on different principles, eg optical IMWs, which operate on the basis of optical phenomena such as the dispersion of light or the phase shift method, or electronic IMWs based on electronic circuits and components such as transistors or diodes.
To use an IMW, you must first contact the infrared radiation with the IMW by guiding it through or near the IMW. The IMW then converts the infrared radiation into microwave radiation, which you can then measure or use.
It is important to note that the quality of the microwave radiation produced depends on the quality of the IMW and the infrared radiation used. If you want to generate as monochromatic microwave radiation as possible, you should use an IMW that is suitable for the conversion of monochromatic infrared radiation and is based on a principle that generates monochromatic microwave radiation. You should also make sure that the infrared radiation used is as monochromatic as possible.
I can't find that. Do you have a Wikipedia article?
There are a number of internet articles that deal with the conversion of infrared radiation into microwave radiation:
These articles provide more detailed information on various aspects of the conversion of infrared radiation into microwave radiation and might be helpful if you would like to learn more about this topic. There are also many other internet articles and resources that deal with this topic and you can find online.
It is best to produce coherent microwaves directly with a MASER (the analogue to the laser).
Microwaves are around approx. factor 1000 long-wave, that is low-frequency, than infrared.
I don't know any procedure to make IR MW.
The wavelength, or frequency of EM radiation does not change or hardly change (Compton Effect).
If you need a laser in the MW range…The also a precursor of the laser (maser) in the 1950s.
There is a frequency doubler in the optics. Is there a frequency divider?
Of course, there are frequency doublers but also frequency dividers. Only not in the range :1000. Free electron lasers are used to generate coherent microwaves. A fast electron beam is sent through a so-called undulator. This produces a bundled, monochromatic, coherent microwave or X-ray radiation.
You want to convert long-wave IR into short-wave MW. Right?
Then why frequency dividers? Half frequency would be double wavelength…
My mistake…
Who can read correctly is clearly in the advantage…
Um… Microwaves are much longer-wave (so low-frequency) than infrared… Rough factor 1000….
This should be done via non-linear optical effects, eg by differential frequency generation or down conversion. But you need a correspondingly ground non-linear optical crystal. And these processes are usually very inefficient, so much of your IR radiation will be lost to you.
Not in a ratio of 1000!
