Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can ...
Abstract: Laser diodes with narrow linewidth are essential for optical communication, spectral analysis, and precision measurement. This study reinterprets the linewidth narrowing mechanism in ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, ...
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.
ABSTRACT: In this article, we report on a ring-cavity diode laser configuration, which has more features compared to the standing-wave external-cavity diode lasers. First, a transmission grating will ...
