2000 nm Tunable External Cavity Laser Source

Based on our electrically tunable filter, we release the tunable external cavity fiber laser for the 2000 nm band. The laser can perform continuously over up to a 90 nm tuning range. The laser is controlled by a computer in a user-friendly interface through the USB port. The tuning speed, resolution and the scanning range can be easily set in the interface window.

With model number OETLS-300-2000, this compact, rugged laser provides high output power and high side-mode suppression ratio (SMSR) and excellent linear wavelength-scanning, which is a cost-effective OEM product for system integration applications or turn key solution for laboratory purposes and industry applications.

Interface:

The main windows of the interface look like Fig. 2, where the user can easily control the device parameters (such as: resolution and tuning speed), set the target wavelength and scan (multiple or continuous) between two specified wavelengths. The device could also be completely re-calibrated by the user in the provided calibration window if necessary.
