Here are some SLR2000 papers that are more easily accessible.[1][2]
Doing this with low-power lasers requires rather good receiving optics.
There has been a major breakthrough in laser data transmission - the first cat video has been sent by laser to and from a spacecraft. "At the time, Psyche was traveling 19 million miles (31 kilometers) from Earth, about 80 times the distance between Earth and the Moon. Traveling at the speed of light, the video signal took 101 seconds to reach Earth, sent at the system’s maximum bit rate of 267 megabits per second."[3]
