Engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability ...

Owing to their coherent light-emission properties with high brightness and narrow spectral line width, the most promising lasers of deterministic single photons and entangled photons operated in multi ...

High-power single-frequency fiber lasers with diffraction-limited spots are indispensable for a wide range of photonic applications and are particularly in advanced detection and sensing technologies.

1250 mW of single-spatial mode power from a chip is highest output from one emitter, says Sydney firm. A 67% improvement from the previously reported 750 mW SM performance. BluGlass, a Sydney, ...

Single-mode semiconductor lasers provide an inexpensive and compact laser source for a wide range of applications, including Raman spectroscopy, Raman microscopy, process Raman, metrology, atomic ...

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...
