Abstract
The possibility of laser diodes degradation control by monitoring of their spectrum is shown. For red and infra-red laser diodes, the time dependence of the radiation spectrum width was obtained.
Highlights
In this paper, we studied the spectral characteristics of two sets of eight and four laser diodes KLM650-5-5 and KLM980-5-15, respectively, generating red (650 nm middle wavelength) and infrared (980 nm) light
An important problem in the operation of these devices is the prediction of their service life and the determination of the operating time through which their substitution is required
It is necessary to know which physical processes lead to the degradation of laser diodes
