Progress of Industrial Femtosecond Machining – A Rich 20-year History
Micromachining with femtosecond lasers (also known as ultrafast or ultra-short pulse lasers) is gaining popularity due to several advantageous properties, including the nearly athermal, or “cold,” ablation process. For industries demanding smaller and more precise parts, this technology offers several benefits, including higher yields, tighter tolerances, little to no collateral damage, and no post processing.

Catching Molecules in the Act
Chemical reactions are characterized by the motion of atoms; transformation of chemical compounds, reactants, and raw materials is therefore governed by molecular vibrations. While the motion of the atoms is easily seen at the beginning and end of a chemical reaction, the molecular changes occur too rapidly in the middle of the process, making them […]
Synchronization of a 25 MHz Magellan Yb-doped Fiber Oscillator with a Streak Camera from Optronis
Clark-MXR, Inc. is pleased to announce the first demonstration of a Yb-doped femtosecond fiber oscillator running at 25 MHz successfully synchronized with a Streak camera. This is a result from a collaboration with the companies Optronis GmbH (Dr. Patrick Summ, [email protected]) and Horiba Scientific GmbH (Dr. Hans-Erik Swoboda [email protected]) from Europe. The Magellan is a telecom-qualified […]
Observation of Rapid Exciton–Exciton Annihilation in Monolayer Molybdenum Disulfide
A publication from Prof. Tony Heinz group with Model IMPULSE from Clark-MXR. Dezheng Sun, Yi Rao, Georg A. Reider, Gugang Chen, Yumeng You, Louis Brézin, Avetik R. Harutyunyan, and Tony F. Heinz Monolayer MoS2 is a direct-gap two-dimensional semiconductor that exhibits strong electron–hole interactions, leading to the formation of stable excitons and trions. Here we report the existence of efficient exciton–exciton annihilation, a four-body interaction, […]

DNA Extraction from Geological Samples Assisted with Clark-MXR Femtosecond Laser Micromachining Technology
Traditional techniques used to extract DNA from thin sections of rock samples for amplification and analysis will often introduce contamination from the surrounding material. This is especially true when extracting microscopic inclusion in the presence of nearby unwanted materials. Our femtosecond laser micromachining capability offers a way to address these critical concerns. This image shows […]
