1550 nm Tunable External Cavity Laser Source

Based on our electrically tunable filter, we release the tunable external cavity fiber laser for C and L bands. The laser can perform continuously over a 50~90 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, 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 general test, and laboratory purposes.

Interface:

The main windows of the interface look like Fig. 3, 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.
