Ceramics are popular dielectric materials known for their exceptional properties, including thermal conductivity, electrical insulation, mechanical strength, and resistance to corrosion and wear. Femtosecond lasers offer a solution for processing hard and brittle materials like ceramics, ensuring the highest quality and accuracy.

A novel approach to increasing the throughput is the use of GHz bursts, which are trains of femtosecond pulses with intra-burst repetition rates in the GHz range. This technique effectively splits a single high-energy pulse into multiple smaller pulses, maximizing the laser power and increasing processing throughput.

Processing semiconductor materials such as Gallium Arsenide (GaAs) using ultrashort laser pulses presents unique challenges due to heat accumulation and the need for precise, high-quality modifications. Femtosecond lasers are particularly well-suited for this task, offering minimal thermal impact and high precision.

Float zone silicon wafer (FZ-Si (100), 0.4 mm thickness) was processed with FemtoLux 30 resulting in high processing quality – low heat affected zone and absence of damage on the bottom surface.

SSAIL is a new technology developed by Center for Physical Sciences and Technology and Akonner for writing electronic circuits directly onto the dielectric material.

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.
