Abstract
Relationships of laser diodes' (LD's) noise and reproduced video picture quality are experimentally studied. Single longitudinal mode LDs usually gave acceptable quality, but when these LD's oscillating mode transit to another state through quasi-multi mode, bright spots randomly appeared on the picture. When using multi longitudinal mode LDs, the picture quality were slightly poor and unacceptable, but did not show drastic degradations at any temperature. It was found that good quality of the picture required the LD's RIN to be less than 10 -14 level.
