High-energy lasers have driven many new areas of research, including high-field physics, attosecond spectroscopy, and laser particle accelerators.

Vertical external cavity surface-emitting lasers (Vecsels), also known as semiconductor disc lasers (SDL), are a relatively new member of the laser family.

a wide-spectrum second-harmonic excitation and multi-frequency conversion process are realized,providing a new solution for...

Researchers in Germany have developed a novel method of optical signal control by combining femtosecond laser writing and liquid crystal electro-optic modulation.

Super ultra-short lasers generally refer to laser pulses with pulse widths of tens and hundreds of femtoseconds, peak power of terawatts and petawatts

Compared with InGaAs APD photodetector, single-photon detectors based on InGaAs APD photodetector have higher response speed

There are significant differences in the fabrication process and cost of InGaAs photodetectors with different structures.

High repetition frequency extreme ultraviolet light source has been widely used in the study of electron dynamics

This advance not only optimizes the measurement resolution of extreme ultraviolet light sources, but also provides new possibilities for future...
