Hydrocarbons absorption spectrum

Hydrocarbons absorption spectrum

Depending on the material, the C-H fundamental absorption band is located in the 3.3-3.4 µm window. At these wavelengths, laser-matter interaction can be > 100 times more efficient than with near-IR lasers.

For industrial applications, the FEMTUM UltraTune 3400 combines the strong laser absorption of a UV laser (without denaturating the polymer) and the reliability and beam quality of a fiber laser.
