 It's 785nm 350mW Near infrared 0.2nm spectral linewidth laser source . This laser coupled a 100μm fiber. This is a narrow linewidth laser, usually used for laser Raman experiments. Let's check it now. The 785nm narrow-linewidth Raman laser produced by our company has narrow spectral line width and good spectral stability, and it has a wide range of applications in Raman analysis. Provides free optical path and fiber-coupled two kinds of production solutions, which can be matched with Raman probes and corresponding accessories, to fully solve the customer's need to build a hardware part of the Raman spectrometer. The Raman laser has good spectral stability, and the center wavelength remains basically constant under long-term working conditions; the spectral line width is narrow, and it has a very good Raman effect when used as a Raman light source, and is very suitable for pulling. This 785nm raman laser's datasheet .

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...
