Scientists working on laser applications have developed a new technique using BiBurst mode, for high-efficiency and high-quality ablation of silicon. The team has demonstrated that the BiBurst mode can ablate silicon at a volume rate 4.5 times faster than the single-pulse mode with better ablation quality when delivering the same amount of total laser energy used … Continue reading
Microfluidic channel surface roughness might be a concern in direct femtosecond laser ablation, normally yielding an RMS value in the range of a few µm. One solution to improve this value is using the fs bi-burst regime. In an article, entitled “Fabrication of Microfluidic Tesla Valve Employing Femtosecond Bursts,” it is shown how fs-burst mode ablation … Continue reading
In a video, Access Laser interviews co-principal investigators Professor John A. Sorensen DMD, PhD and Professor Hai Zhang DMD, PhD of the Department of Restorative Dentistry’s Biomimetics, Biomaterials, Biophotonics, Biomechanics & Technology (B4T) Laboratory at the University of Washington. These dental researchers discuss their work utilizing an Access Laser 9.3 µm DL500 all-tissue dental laser. … Continue reading
Many applications in the solar panels and microelectronic industries require parallel ablation or scribing of lines on a flat substrate. Two of these applications are scribing of electrodes and copper removal. These sorts of applications can use Multi-Spot Beam Splitters, along with a scanner. Multi-Spot Beam Splitters are a type of Diffractive Optical Element (DOE) … Continue reading
