Dimension Ultra-narrow linewidth laser source Module is a low-noise Single Frequency fiber laser based on Distributed Feedback Bragg Grating (DFB) technology. It has independent intellectual property rights and achieves a stable single-frequency laser output with single longitudinal mode, linear polarization, and narrow linewidth.
Ultra-narrow linewidth laser source Module has very low phase and frequency noise and low relative intensity noise (RIN). Dimension uses unique packaging technology to ensure low-noise DFB single frequency fiber lasers with excellent wavelength stability.
Dimension uses extra-cavity technology to significantly suppress the relative intensity noise (RIN) of the DFB single frequency fiber laser, ensuring that the resonant cavity of the single frequency fiber laser is not disturbed. Thanks to RIN suppression technology, Ultra-narrow linewidth laser source Module's relaxation oscillation peak intensity noise is reduced by more than 40dB.
Ultra-narrow linewidth laser source Module is based on erbium-doped fiber with ultra-narrow linewidth (<1kHz) and very low phase noise and frequency noise. The standard wavelength is 1550.12nm, and the optional wavelength range is 1530-1570nm, such as the standard wavelength under the ITU framework. Other wavelengths can be customized according to requirements.
