Abstract
Laser icommunication iis ione iof ithe ikey iareas iin iwireless iCommunications. iThis ipaper ideals iwith ianalysis ioptimization, idesign, iand isystem ilevel idevelopment iof isignal iCommunication ithrough ilaser ibeam ibetween itwo isources. iSuch isystem iworks ianalogous ito ifiber ioptic isystem iexcept ithat ithe ibeam iis itransmitted ithrough ifree ispace. iWhile ithe itransmitter iand ireceiver imust irequire iline-of-sight iconditions, ithey ihave ithe ibenefit iof ieliminating ithe ineed ifor ibroadcast irights iand iburied icables. iLaser icommunications isystems ican ibe ieasily ideployed isince ithey iare iinexpensive, ismall, ilow ipower iand ifree ifrom iradio iinterference.
