Researchers from the National University of Defense Technology have developed a novel composite fiber Bragg grating using ...

Abstract: A novel miniature linear motor actuator based on the Piezo Walk principle with a highly dynamic sweep mode combines long travel ranges to 20 mm and speeds to 10 mm/sec with sub-nanometer ...

Raman Scattering in fiber is a nonlinear process that converts some of the photons at fiber laser wavelength to photons at relatively longer wavelength. The higher the laser power the stronger the ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

Fiber sensing scientists from Shenzhen University have developed an encrypted fiber optic tag that can be used for all-optical labeling and recognition of optical transmission channels such as access ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and ...
