1550nm 1MHz Spectral Linewidth Laser PM1550 Fiber Output
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.

SM Fiber Laser System SLD Broadband Light Source
SLD broadband light source adopts super radiant semiconductor diode light-emitting chip, which outputs broadband spectrum with low coherence degree and high output optical power spectral density. The operating wavelength can be selected from O, S, C, L and other bands, suitable for optical OCT, optical fiber sensing applications.
This is a 1550nm 10mW SLD light source of module type. It is equipped with a single mode fiber. It can be customized power adjustable version. When the power adjustment is selected, the power adjustment is controlled through the RS232 serial communication. The standard version is a fixed power mode, the light source is controlled by the button. We tested it with an infrared photosensitive film, and we could see a light spot.
