Ultrafast Fiber Femtosecond Lasers

Ultrafast Fiber Femtosecond Lasers

Ultrafast fiber lasers are on the order of picoseconds and femtoseconds. Ultrafast fiber lasers can be understood as ultrafast technology + fiber lasers, which is to realize ultrafast lasers through fiber media. Therefore, it also has the dual advantages

I. What is an ultrafast fiber femtosecond laser

Femtosecond fiber lasers are femtosecond pulsed lasers mainly based on optical fibers, including gain media made of optical fibers, mode-locked resonators made of optical fibers, etc. Fiber femtosecond lasers are considered to be a new generation of femtosecond lasers due to their advantages of miniaturization, portability, air cooling, low cost and high stability, and are the core seed light source of fiber frequency combs. Basic scientific instruments.

2. Basic principles of ultrafast fiber femtosecond lasers

As the core component of many ultrafast laser application systems, the performance of ultrafast fiber lasers is the primary limiting factor for the entire application system. However, there are still many areas that need to be improved and improved in terms of performance of ultrafast fiber lasers, so the improvement of its performance is still one of the current research directions of ultrafast fiber lasers. In the future, narrower pulse width, higher power output, higher repetition rate, pulse shape, and expansion of pulse wavelength range are the key areas that researchers will focus on. Only when the overall performance of each dimension is steadily improved can it better meet the application needs of different fields.
