Green laser pointers have existed for 25 years, but they produce light only in a narrow spectrum of green and are not integrated in chips where they could work together with other devices to perform ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and ...

Byspeed 3015 laser cutters feature 5,200-W resonators with adaptive radius control (ARC). ARC provides automatic optimization of beam diameters for cutting sheetmetal and other materials. This ...

Output couplers are used predominantly in laser resonators to extract the beam. The laser resonator is optimised through suitable choice of degree of reflection of the output coupler. Output couplers ...

The research team at Fraunhofer IAF has succeeded in combining two active media, an NV diamond and a laser diode, in an optical resonator and thus demonstrating the laser threshold for the first time.
