Single-frequency narrowband Erbium laser


  • Interferometric measurements
  • Measurements of surface velocity in fast-moving, shock-wave processes
  • Vibrometry
  • Laser spectroscopy
  • Optical communications


Erbium single-frequency narrowband fiber laser with low noise level. Stability of laser parameters is achieved by active temperature stabilization in a wide range. The laser has small dimensions and can be built into a standard 19” rack or have an OEM design.

Due to the user-friendly front panel interface and flexible Ethernet (TCP/IP) interface, the laser can easily be used for research purposes in laboratories and measurement facilities.
