NIST scientists have made a breakthrough in laser technology by filling the "green gap" with new microresonators that ...

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

“Previously, we could make big changes — red to orange to yellow to green — in the laser colors we could generate with OPO, but it was hard to make small adjustments within each of those color bands,” ...

Scientists from the National Institute of Standards and Technology (NIST) have now bridged the “green gap” by modifying a tiny optical component a ring-shaped microresonator small enough to fit on a ...

The Mark VII laser resonator utilizes KTP OPO technology to produce the 1.57µ output that is Class I eyesafe, making it usable under all operational and training conditions.

High efficiency and broad wavelength coverage can be obtained by using an Optical Parametric Oscillator (OPO) for the down-conversion process. When pumped with a single-frequency continuous-wave (CW) ...

Fig. 3. (a) Layout of the 2-resonance laser spectrometer and (b) a sub-Doppler spectrum of acetylene measured using the setup. Owing to double-resonant excitation and narrow linewidth of the CW-OPO, ...

When we first heard of [Ildar Rakhmatulin’s] plan to use OpenCV on a Raspberry Pi to detect mosquitos and then zap them with a 1 watt laser, we thought it was sort of humorous. However ...

Laser levels offer precision, reliability, and a measure of safety. Unlike traditional bubble levels, laser levels project a beam of light that serves as a reference point for various construction ...

Rotary laser levels are invaluable tools on jobsites where maintaining accuracy over a wide area or a long distance is crucial. They determine slopes and grades as well as horizontal and vertical ...

When the first laser and inkjet printers for PCs arrived—in the mid-1980s—each could print only in monochrome, and their respective advantages were obvious. The differences are more nuanced ...
