Polymers and their polyimide subset are common in high tech manufacturing because they are mechanically stable, are good electrical insulators, and are inert. They are often used as:
- Printed circuit boards (PCBs),
- Substrates …
Early proponents of laser technologies believed they could push the frontiers of optical imaging and measurement techniques, from interferometry to radar. Yet lasers were not developed with a specific application…
Eliminating the Heat-Affected Zone
Heat is energy transfer from one location to others. How much and how quickly the energy is transferred is determined by the material’s properties: thermal conductivity, heat diffusivity, etc. Generally, metals h…
The ablation process is the underlying mechanism for laser machining. Conventional pulsed-laser machining techniques dissociate matter at atomic and molecular levels via the deposition of laser radiation. The absorbed laser energy is transferred to t…
Humans have been working with glass for millennia, but it has been considered a luxury commodity for most of that time. It was not produced at industrial scales until the…
Chirped pulse amplification (CPA) is a Nobel-prize winning technology that was first developed in the 1980s, but it was not acknowledged by the Nobel committee until 2018. Almost forty years have been spent commercializing this technology, and it now…
IMRA’s FCPA DE and DX femtosecond fiber lasers provide a unique advantage over continuous wave or long pulsed laser sources in that they allow people to decide if, when, and at what specific location they would like a transparent material to become n…
