Abstract

The study investigates the thermal characteristics of high-power laser diodes and evaluates the effectiveness of passive heat dissipation in medical laser systems. Experimental measurements of optical power and diode temperature were conducted for various wavelengths (810, 940, 975, 1064, and 1470 nm) at different operating currents. The dependence of power thermal drift on current and wavelength was observed, as well as the effectiveness of design solutions with passive cooling and combined cooling (passive cooling with forced air convection).
