CW Single-frequency 1.5 µm Fiber Laser OEM Module

Optromix SFESM is a single-frequency low noise 1.5 µm or 1 µm wavelength fiber laser module with wide-range thermal wavelength tuning and fast piezo tuning using an external PZT driver. The SFES, SFEM, and SFYS key feature is the ultra-narrow linewidth based on the longitudinal single mode. In the standard version, these models provide an optical output using a PM fiber patch cord with an FC/APC connector. These modules are controlled via an Ethernet port or via an RS-232 connector using a software supplied with the device. API documentation is provided.
