3MHz Narrow-Linewidth Laser 1570nm 400mW SM Fiber Coupled Laser Module Type FL-1570-400-SM-M21/M31
The 1570nm band single wavelength laser uses a high-performance butterfly-shaped semiconductor laser chip. Professionally designed drive and temperature control circuits ensure the safe operation of the laser, and the output power and spectrum are stable. It is suitable as a pump laser source for thulium-doped fiber lasers or fiber amplifiers, and can be provided in desktop or modular package.
