Transmit power for low/high wavelength

Photons with a shorter wavelength and a higher frequency have more energy than those with longer wavelength. I am sure if we have low wavelength we will have more power and if we have high wavelength,...

What are the reasons for the specific operating wavelengths chosen for laser communication?

As mentioned, in the other answer, cost and availability for 780 and 1064 are important. At the systems level, You also may want to use a cheaper silicon imagining detector to detect your beacon. ...

What are the reasons for the specific operating wavelengths chosen for laser communication?

Beacon wavelength window is 780 to 1064 nm, for data transmission is 1520– 1560 (1600) nm. Could someone explain why beacon signal operates in lower range? I don't have the book handy, but I can ...
