CW Single-frequency DFB 1.5 µm Fiber Laser

Optromix SFEX benchtop model is a single-frequency low noise 1.5 µm (1530 nm – 1580 nm) wavelength Erbium fiber lasers with a wide-range thermal wavelength tuning and a fast piezo tuning using an external PZT driver. The SFE key parameter is the ultra-narrow linewidth based on the longitudinal single mode. In the standard version, this model provide an optical output using a PM fiber patch cord with an FC/APC connector or with an armed fiber cable with a collimator. These models are controlled via USB port using a software supplied with the device. SFE model can be equipped with an additional low power optical output for the wavelength monitoring.
