Free space laser communication refers to the optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. Free space refers to the vacuum, outer space or air.
the laser was invented.....
construction and working of semiconductor laser
If the laser is in Hollywood it is possible, anywhere else in the world? no, impossible
Low, medium and high frequencies is ideal for long distance communication but it is very sensitive to QRM and QRN because only amplitude modulation can be used on this part of the RF spectrum, FM modulation is not possible, where in the higher frequencies, FM (Frequency Modulation) is a beter option but with the drawback of distance overland. VHF, UHF and UUHF can't overcome obstacles like hills, mountains and large buildings, only line of site communication can be used here, although it can be used for long distance in open space IE. in outer space, like satellite communication.
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.

A laser link is an optical communication technology which uses light moving around in free space to transmit data for telecommunications or computer networking. This technology is quite useful rather than utilizing traditional optical fiber cables and transmission lines which constitute more "physical" uses of channels. Examples of laser link use is in spacecraft and satellite which send signals to earth and throughout space.
Laser light is transmitted through specialized optical components such as lenses, mirrors, and fibers. These components are designed to control and guide the direction of the laser beam while maintaining its intensity and coherence. Lasers can also be transmitted wirelessly through the air in free-space communication systems.

LASER application in optical communication
no. LASER uses light frequencies.
There's no set limit, it depends on the power of the laser and the sensitivity of the receiver.
Laser, all the others are bodies/things in space.
Yes, it will.
