The 1550nm band single-wavelength laser (low power) adopts high-stability semiconductor laser chip, single-mode or polarization maintaining fiber output, professionally designed drive and temperature control circuit control to ensure the safe and stable operation of the laser.

It is  a 1550nm 20mW fiber laser source benchtop. PM1550 polarization maintaining fiber is installed, and SM single-mode fiber can also be customized. The output power can be adjusted, and the adjustment accuracy is 0.1mW. This is a narrow linewidth laser with a spectral bandwidth of less than 1MHz. Narrow linewidth lasers at the kHz level can also be customized.
Software control function can be customized,using RS232 communication serial port. Default only supports button control. The standard version is controlled by buttons to control the switch and adjust the power.
