Why Upgrade an Interferometer?

Upgrading an old interferometer is one-third the cost of buying a new one. Watch Äpre’s video for a quick explanation of why you should upgrade your interferometer instead of buying new. What does it mean to upgrade a laser Fizeau interferometer? Äpre basically upgrades the electronic components and software. These include: a new 1-megapixel measurement … Continue reading

Lasers Induce Localized Cross-Linking Reactions in Non-Photosensitized Polymers

A research team has demonstrated that non-amplified femtosecond laser systems delivering 40–500 pJ individual pulses are sufficient for inducing localized cross-linking reactions within hundreds of nanometers in cross sections of non-photosensitized polymers. This experimental work is of high importance for the fundamental understanding of laser-enabled nanoscale 3D additive manufacturing. This research also widens the technology’s field of applications where … Continue reading

Lasers with DOEs Cut Glass More Accurately

Did you know lasers can cut glass tubes and cuvettes? With ultrashort pulsed lasers and Holo/Or’s special curved glass cutting diffractive optical elements (DOEs), you can cut up to several mm of curved glass tube with a spot as small as 3 µm! Laser glass cutting is often done by axicon-generated Bessel beams that get … Continue reading
