A device to protect a pump laser that transmits specific wavelengths such as 975 nm and blocks specific wavelengths such as 1064 nm and 1550 nm.
It has excellent characteristics such as low insertion loss, high extinction ratio, and high stability. Ruik is a leading company in China that manufactures passive fiber components used in optical communication, fiber lasers, and fiber sensor applications. The high-power components for fiber lasers/fiber amplifiers can support up to 40W (average power) and 10kW (peak power). Additionally, the polarization-maintaining (PM) type is offered at high quality and reasonable prices, receiving high demand. Proposals can be made for quantities starting from one unit.
