kHz 1.0µm Narrow Linewidth Single Frequency Fiber Laser

Fiber laser components, Fiber laser modules

The CKSF-R 1.0μm Single Frequency Fiber Laser is an ultra-low noise laser with a narrow linewidth in the low kilohertz range, below 1 kHz. This narrow-linewidth fiber laser delivers ultra-low phase noise and relative intensity noise, with a side-mode suppression ratio (SMSR) over 55 dB. Its high-intensity package allows the fiber laser to operate reliably in various environments, ensuring stable single longitudinal mode output and mode-hop-free performance even under temperature variations, vibration, or shock. The output power is at the mW level, with higher power available upon request, and the wavelength is tunable in the 1010–1120 nm range.

The CKSF-D 1.0μm Single Frequency Fiber Laser is a low-noise, narrow-linewidth fiber laser designed using distributed feedback Bragg grating technology. It achieves stable linear polarization, single longitudinal mode, and ultra-narrow linewidth single-frequency output. The laser features ultra-low frequency and intensity noise, with output power reaching 50 mW and a wavelength range of 1010–1120 nm.
