Narrow-Linewidth Fiber Lasers

BIRKEROD, Denmark, Sept. 27 -- Koheras is expanding its line of low-noise, narrow-linewidth distributed feedback (DFB) fiber lasers with an OEM version of its Boostik E15/C15/Y10 products, by offering up to 2-W continuous wave (CW) optical output.
The devices are packaged in a rugged carbon-shielded OEM module with a digital RS232 interface and a software program with several control/monitor options.
Koheras said the lasers feature very stable single frequency and mode-hop-free operation, with a narrow spectral linewidth of a few kHz, exceptionally low phase and intensity noise and rapid piezo tuning. They were designed for operation in harsh environments with reduced susceptibility to acoustic noise and vibrations.
The lasers cost little to maintain and are compact and easy to assemble, the company said. They also feature embedded electronics and computer interface for device control and monitoring and high wall-plug efficiency.
The lasers are available at 1530- to 1580-nm wavelengths; other wavelengths are available in the 1-micron range, such as 1064 nm. Lower output power versions are also available with a smaller footprint. The module is delivered with FC/APC SMF-28 pigtailed output, PM or non-PM, and can be supplied with a free-space collimated output.
Applications include spectroscopy, trapping, Lidar, wind sensing, sensor interrogation (e.g., security and oil exploration) and other applications relying on stable single frequency operation and narrow linewidth/long coherence.
