High Precision Processing of Flexible or Thick Glass

Processing (cutting or micro-structuring) tempered or non-tempered, flexible or thick glass with high precision can be a challenging task. Mesh glass wafers and wafers for wafer-level-packaging (WLP) require various shapes of through-holes with high aspect ratio channels in the same wafer. Femtosecond lasers are perfect for both selective laser etching (SLE) and 5-axis drilling heads. … Continue reading

Using PHAROS Femtosecond Laser for Laser Lithography

Ceramics and ceramic-like materials are essential in science and industry due to their outstanding thermal, mechanical, chemical properties. In a recent article, PHAROS femtosecond laser from Light Conversion was used for laser lithography of hybrid organic-inorganic materials with subsequent heat treatment leading to tunable-crystalline-phase 3D nanostructures with feature resolution down to 60 nm. The article, entitled “Laser additive manufacturing of Si/ZrO2 tunable crystalline phase … Continue reading

Measurement of Transient Optical Fields

The measurement of transient optical fields is critical to understanding the ultrafast physical and chemical phenomena and is key to realizing high-speed electronics and telecommunications. In a paper entitled, “Single-shot measurement of few-cycle optical waveforms on a chip”, a technique is demonstrated for single-shot waveform measurement of few-cycle mid-infrared pulses. The abstract of this paper states: “The … Continue reading
