pumping current of the heat sink. Current intensity distribution in the points of
the interferogram under study and its modification were recorded with a system of
recording photodetectors. Real-time interferograms of the laser diode mirror under
the current I are presented in Figs. 2.44 and 2.45.
Heating of the diode as well as of the heat sink occurs under continuous generation
of the laser diode. As a consequence of this, the recorded shift of the diode facet x d
