Low phase noise fiber laser allow extending optical sensing

Nowadays the use of fiber lasers in interferometric optical sensing and other fiber-optic systems has allowed extending their reach all around the world. Until recently all fiber lasers contained an amount of noise because of the influence of quantum noise and technical vibrations. Quantum noise may be presented in a system where conventional sources of...


Novel Femtosecond Lasers’ Application for Spaceflight Technologies

A team of researchers at NASA’s Goddard Space Flight Center has shown that it’s possible to weld glass to copper, glass to glass, and drill hair-sized pinholes in different materials for use in spaceflight applications. This research group is expanding its research into a more exotic glass, such as sapphire and Zerodur, and metals, such...


Raman Scattering in High Power Fiber Lasers in Cancer Diagnosis

Lasers, specifically fiber lasers, are already implemented in medical diagnosis, treatments, and therapies. Scientific laser systems are promising for many fields of medical studies, one of them being cancer research and treatment. Cancer is one of the leading causes of morbidity and mortality worldwide with approximately 14 million new cases and 8.8 million cancer-related deaths...


What the Future Prospects May Bring in Femtosecond Laser Applications

The femtosecond laser is an infrared laser (wavelength: 1,053 nm) with an ultrashort pulse duration (10-15 s). The early femtosecond laser systems operated with a low repetition rate (15 kHz) and thus required higher energy to operate. The new devices have an increased repetition rate (as high as 150 kHz), which leads to the utilization...
