Photonwares produce high performance Fiber Coupled Single Frequency Lasers.  It features ultra-narrow single frequency linewidth, single mode, single longitudinal mode, polarization maintaining output, high optical power, excellent output stability over a wide temperature range and without mode hopping, high efficiency, low cost, and high reliability. The unit is made based on Er-doped fiber and distributed feedback Bragg grating technologies. It incorporates extra-cavity to achieve low phase and low relative intensity noise (RIN). The laser source is covered by a 2-year warranty.

The laser source can also be configured as a turn key unit with build-in controller for lab use.  Photonwares also provide customers design. We provide output beam collimator, as well as wavelength stabilization choices.
