1050nm ASE Light Source

Amonics' ALS-1050 series offers a Ytterbium-doped fiber ASE broadband light source in the wavelength range of 1000nm to 1100nm, offering 10mW and 20mW output power. It is particularly useful for 1060nm fiber laser component characterization.

The benchtop version incorporates a user-friendly front panel housing a LCD monitor display, key switch, power control knob and optical connectors. RS232 or Ethernet computer interface is also equipped.

The OEM module version is an ideal building block for OEM system integration, especially for fiber optical sensing and optical tomography applications. It requires a single +5V power supply only.
