Present day optical wireless communication systems work with wavelength of 1550 nm but it is considering whether optical communication at 850 nm offers more benefits. Currently we don't know answer on the question which optical window is more reasonable to use in free space optical links but we try to solve this problem. This paper is focusing on the relation between laser diode operating temperature and spectral linewidth. We select laser diode which emits wavelength of 1550 nm (RLT1550-15G). The point of the research is to examine spectral properties of this laser diode in relation to increasing laser diode operating temperature.
