Optromix DSEL

CW Single-frequency 780 nm (775 nm, 778 nm) Fiber Laser

Optromix DSEL model is a single-frequency narrow linewidth low noise 780 nm (775 nm, 778 nm) wavelength lasers with a wide-range thermal wavelength tuning and a fast piezo tuning using an external PZT driver. The DSEL key parameter is the ultra-narrow linewidth based on the longitudinal single mode. In the standard version, this model has an optical output to the free space from the laser head, but optionally, it can be equipped with the PM fiber output using a fiber port. This model also can be supplied with an additional low power optical output of a first harmonic for the wavelength monitoring. Optromix DSEL can be computer controlled via USB connection using software supplied with the device.
