Definition of degradation degree of single – mode laser diodes, used in laser masuring, by their emission spectrum

Hereby the possibility of determining of the degradation factor of single-mode laser diode with the use of it's emission spectrum width, measured at level 0.2 from the maximum value of the intensity at the peak is shown.
