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.
Semiconductor laser diode, which can directly convert electrical energy into light energy, has the characteristics of high brightness, high efficiency, long life, small size, and direct modulation.
Since the advent of the first solid-state pulsed ruby laser, the development of lasers has been very rapid, and lasers with various working materials and operating modes have continued to appear. Lasers are classified in various ways:
