Investigation of the Effect of Temperature Stabilization in Radiation-Heat Converters Based on a Strong Absorbing Coating

Light-heat converters are promising for further development of contact laser surgery. The simplest converter consists of an optical fiber with a strong absorbing layer at the tip. We studied the time dependence of the tip temperature at different CW laser powers and revealed that, in several seconds, the temperature evolution becomes almost power-independent. Mathematical modeling showed that laser ablation of the tip coating is the main reason for this phenomenon.

Automated summary

Light-heat converters made of optical fibers with a strong absorbing layer at the tip can achieve stable temperatures at different laser powers. Research revealed that laser ablation of the tip coating is the main reason for this phenomenon.
