PM Optic Fiber Laser@1570nm 50mW 3MHz Narrow-Linewidth DFB Laser Diode FL-1570-50-PM-M15 Module Type
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.
