A duplex laser communication transceiver, and a method for its operation, in which the effective rates of data transmission on a transmit laser beam are adaptively controlled in response to detection of the instantaneous power of a receive laser beam. Variations in laser beam power caused by atmospheric turbulence are sensed in the transceiver, and effective data transmission rates are controlled appropriately to avoid or minimize data errors. Data bits input to the transceiver for transmission are stored in a data buffer; then retrieved at a rate that is varied in accordance with the instantaneous power. The transmit data rate is decreased or suspended when the laser beam power is low, and increased again when the laser beam power is high. Data signals recovered from the receive laser beam are also buffered, to obtain an output data stream at a uniform rate.
