摘要： Methods, devices, and systems are described for free space optical communication. An example device can comprise a defocuser configured to receive an optical signal from a laser and control a beam divergence of the optical signal. The device can comprise a controller configured to cause the defocuser to adjust the beam divergence based on an operational mode of the laser.
