Femtosecond Laser Micromilling Application Examples: Serial Sectioning and Wear-Defect Simulation

Femtosecond laser micromilling, or ablative laser processing, removes material in, virtually, any shape or pattern. Cut widths down to a few microns are achievable and sub-micron kerfs are possible for very thin materials. Femtosecond laser machining enables repeated manufacture of precision components with complex patterns. 3D blind features can be created with depth resolutions within a few percent of the feature depth and resolutions as high as a few 10's of nanometers can be performed on production parts. Serial SectioningApplying ablative, or subtractive, patterning processes to an entire material surface [...]

Congratulations Gerard!

Clark-MXR would like to congratulate this year's Physics Nobel laureates, Professors Gerard Mourou and Donna Strickland for their invention of Chirped pulse amplification and Professor Arthur Ashkin for optical tweezers. For Clark-MXR, this is a joyous occasion as Prof. Gerard Mourou is one of our co-founders and our CPA-Series laser, first introduced in 1992, is named after the Chirped Pulse Amplification technique that Profs. Gerard Mourou and Donna Strickland are honored for. We congratulate all three recipients of the Physics Nobel prize and especially our co-founder, Prof. Gerard Mourou.

Achieving Lower Costs with µManufactured Components and Assemblies for OEM Instrument Manufacturers

THE CHALLENGE Manufacturers of analytical and diagnostic instrumentation have ongoing pressures to reduce costs. Use of ultrafast laser micromachining processing methods, by Clark-MXR, has improved customer's bottom lines by providing new, groundbreaking capability for producing microscopic machined features on engineered components. Clark-MXR's leading edge laser micromachining technology coupled with micromanufacturing expertise, cleanroom inspection and packaging capabilities offer far reaching value propositions for customers. Optical, X-Ray and electron beam-based instruments, such as spectrometers, electron microscopes and X-Ray tools are dependent, in part, on high precision internal componentry that enable [...]

Ultrafast Laser Micromachining Creates Surface Modifications to Assist R&D Developments

Ultrafast laser micromachining of surface modifications produce geometrical structures that conduct very precise functions. As the demand for device miniaturization continues, ultrafast or femtosecond laser micromachining produce surface reliefs on a micrometric or even nanometric scale and with high aspect ratios. Application examples Surface chevrons for enzyme reactions in point-of-care tests Lab-on-Chip microfluidic channels and microholes Security identification markings Creating diffractive, absorbent, adhesive surfaces 3D structuring of dielectrics, silicon, polymers, thin-films, integrated optics

Using Lasers to Produce Faster Electronics and Better Solar Cells

Recently, the concept of integrating photonics and electronics, with the goal of producing faster electronics and more effective solar cells, has been attracting a significant amount of interest. To properly understand this idea, the small-scale electronic and photovoltaic processes must be investigated on the atomic or molecular level. Prof. Hrvoje Petek and his research group at the University of Pittsburgh are aiming to do just that, operating under the notion that processes cannot be controlled until they are adequately measured. To perform their investigations, the research group used [...]

Using Label-free imaging techniques to further understanding of Multiple Sclerosis

Multiple Sclerosis (MS) is an autoimmune inflammatory disease that affects nearly 2.3 million young adults worldwide. In cases of MS, the immune system promotes an attack on the central nervous system (CNS), often leading to disability and degeneration. The MS lesion is traditionally considered the leading indicator of CNS damage and thus has been studied for decades through various clinical pathological methods. However, it has been found that surrounding regions in the brain, known as 'normal-appearing' white matter (NAWM), also present some abnormalities in MS cases. Label-free imaging [...]
