At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
The laser driven particle accelerator on silicon chips was created by two independent research groups. With further improvements, this dielectric laser accelerator can be used in medicine and industry, and even in high-energy particle physics experiments.Accelerating electrons to high energy is usually accomplished over long distances in large and expensive facilities. For example, the electron ac...
Recently, high-power blue laser manufacturer NUBURU announced the official launch of a working group consisting of a joint management team from the company and the target defense technology enterprise, which was part of the previous acquisition plan. According to the joint research and development agreement signed by NUBURU in March, the working group will also be responsible for overseeing the ...
Imagine in such a world, the detection of trace substances is not only fast, but also incredibly accurate, indicating a new era of technological progress in health, safety, and environmental monitoring. Due to pioneering research on plasma waveguide structures, this vision is becoming increasingly realistic, aimed at enhancing refractive index sensing and spectral filtering. This innovative method...
