The invention relates to a portable wireless laser communication terminal machine which belongs to the technical field of communication. The portable wireless laser communication terminal machine comprises a pickup, a sound reproducer, an audio-frequency voltage/power amplifier, a coder-decoder, a microcontroller, a modulation drive circuit, a semiconductor laser, an emission optical system and asignal back-end processing circuit, wherein the signal back-end processing circuit is sequentially connected with a photoelectric detector, a front-end processing circuit and a receiving optical system; the semiconductor laser is a pulse semiconductor laser; the emission optical system collimates light beams emitted by the semiconductor laser, and the value selection range of the divergence angleof the collimated light beams is greater than or equal to 1.5 degrees and smaller than or equal to 12 degrees; and the photoelectric detector and the front-end processing circuit are provided with silicon four-quadrant detectors or indium-gallium-arsenic four-quadrant detectors. The invention realizes signal optical detection and collimation integration, does not need an independent collimation passage for accurately collimating the light beams, does not need an independent beacon optical tracking system and a stabilized platform and enables the volume and the weight of the terminal machine to meet the portable requirement.
