Description
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.
