Heat-sensitive organic material processing with femtosecond laser

Organic materials are typically very sensitive to induced heat, which can cause warping and burnt edges during processing. Femtosecond lasers are an excellent solution for these materials because their ultra-short pulse duration prevents significant heat transfer to the material’s lattice, ensuring high accuracy and quality processing.

FemtoLux 30 laser was used to process thin organic materials for medical applications. These materials are particularly susceptible to thermal accumulation. By utilizing the short pulse duration of 350 fs and combining it with high scanning speeds, the cutting of these thin organic materials was achieved without inducing significant thermal effects. Cutting speeds of 100 mm/s was reached, demonstrating the laser’s capability to process heat-sensitive materials efficiently and precisely.
