Abstract: Semiconductor laser diodes (LDs) typically use lattice-matched epitaxial layers as waveguide cladding materials. We describe a new LD architecture in which the upper cladding layer is ...

A compact fiber-based system has been developed to compress mid-infrared laser pulses to 187 femtoseconds using low input power. By integrating a holmium-doped ZBLAN photonic crystal fiber within a ...

Abstract: We demonstrate a double-clad anti-resonant hollow-core fiber (DC-ARF) with an offset inner cladding structure for effective mode tailoring. The DC-ARF consists of six thin-walled, ...

Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear ...

Living with scars can be difficult. A scar can change the way you think about and see yourself, but it can also affect your life in bigger ways. Some scars can even limit your motion. There are ...

Getting rid of your body hair is a personal preference, but aside from whether or not to de-fuzz and how long the removal process might take, there are other things to consider for those with ...

Laser eye surgery uses a laser to change the shape of the cornea and improve vision. LASIK is the most popular form of laser eye surgery, but it may not be suitable for everyone. PRK uses a laser to ...

Robotics startup Sunday hits a $1.15B valuation after a $165M Series B. Learn how their robot "Memo" plans to take over home chores by 2026.

Find information about fire safety rules for external wall cladding for owners, tenants, strata managing agents, building managers and real estate agents. Find out if your building has combustible ...

Cold laser therapy uses low-intensity light to help relieve pain and inflammation. Cold laser therapy is painless and non-invasive but may require multiple sessions. If you have an injury that causes ...

In science fiction, the use of gunpowder-based weapons is generally portrayed as something from a savage past, with technology having long since moved on to more civilized types of destructive ...
