For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and ...

Scientists at NPL recently published findings on laser frequency stabilization, demonstrating an unprecedented level of performance using an optical reference cavity. This advancement features a ...

Researchers developed a new optimized printing approach that could enable super-resolution 3D direct laser writing (DLW) of microlenses, photonics crystals, micro-optical devices, metamaterials and ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand. But ...

External cavity laser diodes (ECLs) are lasers with a very small line width, excellent wavelength stability, and very low noise. They are used in optical communication and fibre sensor technology.

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand. But ...

In recent years, optical vortices have attracted extensive attention in laser advanced manufacturing because of their annual intensity distribution and orbital angular momentum. Compared with the ...
