I tried to locate a free online pdf copy of this paper, and couldn't find one.
https://ui.adsabs.harvard.edu/abs/2000R ... A/abstract
What they seem to have done was to use the built-in photodiode of a laser diode (used for power monitoring) as a controlled heating element for the laser diode chip.
On page 3649 they say: "The thermal control we propose in this article utilizes as a heating element the semiconductor slice of the built-in photodiode which is used for laser optical output monitoring. The built-in monitor photodiode, commonly available in most commercial diode lasers, consists of a chip of rectangular shape deposited directly onto the iron mounting which supports the laser and is placed very near to the emitting source, as shown in Fig. 2 (a)."
So far I haven't located any actual numbers in the paper (in degrees C) to indicate how much heating was involved.
