Description Description
QRTE⁸981-1-XXx-1-0 series 980nm pump laser components are specially designed for low-power fiber amplifiers and ASE pump light sources. The
coupling lens fiber is fixed by low-temperature glass solder, and the low-frequency current laser chip is selected to improve the reliability of the components. sex and stability.
