For spectral synthesis technology, increasing the number of synthesized laser sub-beams is one of the important ways to increase the synthesis power. Expanding the spectral range of fiber lasers will help increase the number of spectral synthesis laser sub-beams and increase the spectral synthesis power [44-45]. At present, the commonly used spectrum synthesis range is 1050～1072 nm. Further expanding the wavelength range of narrow linewidth fiber lasers to 1030 nm is of great significance to the spectrum synthesis technology. Therefore, many research institutions have focused on short wavelength (wavelength less than 1040 nm) narrow line Wide fiber lasers were studied. This paper mainly studies the 1030 nm fiber laser, and extends the wavelength range of the spectrally synthesized laser sub-beam to 1030 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.

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.
