Physicists at Harvard University have developed a powerful new on-chip laser that emits bright pulses in the mid-infrared spectrum—an elusive but extremely useful range of light that can be used to detect gases and enable new spectroscopic tools.
According to the direction of scattered light propagation, currently common distributed fiber optic sensing technologies are divided into two categories: backscattering distributed fiber optic sensing technology and interference distributed fiber optic sensing technology.
A pump laser is a laser used to provide an excitation light source for a fiber laser or fiber amplifier. The emission wavelength of a 980nm pump laser is approximately 980 nanometers (nm).
In recent years, thulium-doped fiber lasers have attracted more and more attention due to their advantages such as compact structure, good beam quality, and high quantum efficiency. Among them, high-power continuous thulium-doped fiber lasers have important applications in many fields such as medical care, military security, space communications, air pollution detection, and material processing. In the past nearly 20 years, high-power continuous thulium-doped fiber lasers have developed rapidly, and the current maximum output power has reached the kilowatt level. Next, let’s take a look at the power improvement path and development trends of thulium-doped fiber lasers from the aspects of oscillators and amplification systems.
Challenges faced by high-power continuous thulium-doped fiber lasers, Over the past two decades, the output power of continuous thulium-doped fiber lasers has increased dramatically. The output power of a single all-fiber oscillator has exceeded 500 W; the all-fiber MOPA structure has achieved an output power of kilowatts. However, there are still many problems restricting further improvements in power.
At the 2023 Indo-Pacific International Maritime Exhibition, Australian Optronic Systems demonstrated its newly developed anti-drone soft-kill solution for the first time.
