The authors describe investigations which confirm the importance of considering laser mode partition noise when practical optical systems are projected. It also gives theoretical estimations and measurement results which are in good agreement, and demonstrates the influence of laser mode partition noise on the transmission quality of an analogue optical system.enlaser beam applicationslaser modesnoiseoptical communication equipmentoptical linksoptical wideband transmission linksmultimode lasersdispersive fibressingle-mode fibresnonzero material dispersionlaser mode partition noisetransmission qualityanalogue optical system621384journal article
