Pulsed Erbium-doped Fiber Amplifier Manufacturers

In recent years, with the continuous expansion of pulsed laser applications, the high output power and high single pulse energy of pulsed lasers is no longer a purely pursued goal. In contrast, the more important parameters are: pulse width, pulse shape and repetition frequency. Among them, the pulse width is particularly important. Almost just by looking at this parameter, you can judge how powerful the laser is. The pulse shape (especially the rise time) directly affects whether the specific application can achieve the desired effect. The repetition frequency of the pulse usually determines the operating rate and efficiency of the system.

Everyone must have heard the slogan "femtosecond laser for myopia", but I believe many people don't know what femtosecond laser is. Similarly, there are nanosecond laser and picosecond laser. What's the difference between these strange seconds and our common lasers?

Fiber lasers refer to lasers that use rare-earth-doped glass fibers as gain media. Fiber lasers can be developed on the basis of fiber amplifiers: high power density is easily formed in the fiber under the action of pump light, resulting in laser working material. The energy level "number inversion" can form laser oscillation output when a positive feedback loop (form a resonant cavity) is properly added.

In the field of optical communications, long-distance transmission has long been challenged by issues such as signal attenuation and distortion. Raman fiber amplifiers, with their unique advantages, have become a key technology for improving the performance of long-distance optical communication systems.

According to the latest report from IMARC Group, the global fiber laser market will grow at a CAGR of around 8% in 2021-2026. Factors such as rapid industrialization and increasing adoption of advanced technologies to automate various manufacturing processes are among the key factors driving the growth of the fiber laser technology market. In addition to this, fiber lasers are gaining popularity in the healthcare industry due to the growing prevalence of chronic diseases. They are used in settings such as dentistry, photodynamic therapy, and biomedical sensing in the mid-infrared spectrum. Furthermore, with the growing demand for electric vehicles (EVs), the application of fiber lasers in internal combustion engines (ICEs) is expected to increase.
