The use of ultrashort pulse synchronous pumping of Raman fiber lasers is another way to achieve wavelength-sensitive Raman pulsed lasers. In the Raman fiber laser, the Raman scattering response speed in the fiber is extremely fast, and the time domain characteristic of the pump pulse can be effectively transmitted to the Raman pulse, and the Raman can be realized without the saturable absorber. Ultra short pulse output. In pulse pumping, the gain is only provided during the period of the pump pulse width, so no spontaneous Raman light and continuous light components are generated in the cavity, and the Raman pulse can be guaranteed as the equivalent saturable absorber. Purity. At the same time, the Raman gain is proportional to the pumping power and does not saturate, so that ultrashort pulse pumping can use its extremely high peak power to provide a higher Raman gain per unit length of fiber, thus effectively overcoming the lock. The shortcoming of the required gain fiber in the mode...

The Raman Fiber Amplifier (RFA) is operated by the third-order nonlinear effect of the strong laser in the fiber-stimulated Raman Scattering (SRS). If a weak signal light is transmitted in a fiber at the same time as a strong pump light, and the wavelength of the weak signal light is within the Raman gain bandwidth of the pump light, the energy of the strong pump light is coupled to the fiber silicon material through the SRS. The oscillating mode is then emitted at a longer wavelength, which is the wavelength of the signal light, thereby amplifying the weak signal light to obtain a Raman gain . Classification of Raman fiber amplifiers RFA is divided into two main categories: discrete (or centralized) RFA and distributed RFA. They have their own characteristics and are suitable for different application areas. The amplification medium used by discrete RFAs is typically a dispersion compensating fiber (DCF) or a highly nonlinear fiber. The gain fiber used is relatively short, ty...
