Laser communications systems are wireless connections through the atmosphere. They work similarly to fiber optic links, except the beam is transmitted through free space. While the transmitter and receiver must require line-of-sight conditions, they have the benefit of eliminating the need for broadcast rights and buried cables. Laser communications systems can be easily deployed since they are inexpensive, small, low power and do not require any radio interference studies. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed, one for transmission and one for reception. Due to budget restrictions, the system implemented in this project is only one way.
Laser communications have been a hot topic lately, as solutions for how to satisfy ever increasing bandwidth needs are in high demand. Some have suggested that bandwidth could be distributed in neighborhoods by putting laser communication systems on top of homes and pointing them towards a common transceiver with a fast link to the internet. With possible transmit speeds of up to a gigabit per second, this is an exciting area. Other applications for this technology include temporary connectivity needs (e.g. sporting events, disaster scenes, or conventions), or space based communications.

Laser polarization can affect the efficiency of optical communication systems by influencing the transmission and reception of light signals. When the polarization of the laser light aligns with the optical components in the system, it can enhance signal strength and reduce signal loss, leading to improved efficiency. Conversely, misalignment of polarization can result in signal degradation and decreased efficiency in the communication system.
The advantages of laser communication is that it allows very fast communication service between two or more devices than other modes of communications.It can provide speed more than 1GBps.So it overtakes the LAN or wireless LAN comprehensively

There's no set limit, it depends on the power of the laser and the sensitivity of the receiver.

Inter-satellite laser communication occurs through the use of laser beams to transmit data between satellites in orbit. These satellites are equipped with laser communication terminals that can precisely aim and establish a line of sight with one another. The data is encoded into light pulses, which are then sent through the vacuum of space, allowing for high-speed, high-capacity communication. This method offers advantages such as reduced latency and increased bandwidth compared to traditional radio frequency communication.
LASIK and cataract surgery can be performed using Femtosecond laser system. This system is useful for cutting a flap of skin off of the front of the eye for some laser surgeries.
