The CKSF-R single frequency fiber laser is a kind of ultra-low noise laser with narrow linewidth in the low kilohertz range which is below 1 kHz. These narrow-linewidth lasers deliver ultra-low phase noise and relative intensity noise, making them ideal as a low phase noise fiber laser for precision optical applications. The side-mode suppression ratio (SMSR) is over 55dB.

Besides, a high-intensity package is adopted to allow the fiber laser to be applicable to various environments, ensuring stable single longitudinal mode output and free of mode-hops even under changing environmental conditions such as temperature variance, vibration, and impact. The output power is at mW level, and higher output power can be tailored to your specific needs. The wavelength is available in range of 1010-1120nm, making it suitable as a 1.0 um seed fiber laser source for fiber amplifier systems and scientific applications.

The CKSF-D narrow linewidth single frequency fiber lasers are low-noise fiber lasers designed with distributed feedback Bragg grating type fiber laser technology, achieving stable linear polarization, single longitudinal mode, and ultra-narrow linewidth single-frequency laser output. The output optical spectrum linewidth is at kHz level, featuring ultra-low frequency noise and intensity noise. The output power reaches 50mW, and the wavelength is available in range of 1010-1120nm.
