Narrow-linewidth fiber laser

The Ultra Narrow Linewidth Laser has linewidth of less than 1 kHz. It features a minimum signal-to-noise ratio of 60 dB and is suitable for sensor application as well as other high-precision measuring techniques. The laser is manufactured by inducing a fiber Bragg grating in the core of an erbium-doped fiber to provide internal feedback. The laser package is 100𨓬䂀 mm and comes with a pump input port and a signal output port. Any center wavelength in the 1520- to 1585-nm bandwidth can be produced.
