CKSF-D Narrow Linewidth Single Frequency Fiber Laser for Laser Spectroscopy
Techwin CKSF-D 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. CKSF-D has very low phase and frequency noise and low relative intensity noise (RIN). Techwin uses unique packaging technology to ensure low-noise DFB single frequency fiber lasers with excellent wavelength stability.
Techwin 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. Please refer to CKSF-D-RS series products.
CKSF-D narrow linewidth single frequency fiber laser module has a small size, a sturdy package, strong resistance to environmental interference, output power is up to100mW. CKSF-D-ER-M is based on erbium-doped fiber with ultra-narrow linewidth (<1kHz) and 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.
Laser spectroscopy is a versatile diagnostic tool for analytical applications and recent advances in fiber laser technology combined with selective and sensitive spectroscopic detection techniques have led to the development of new diagnostic tools for trace gas and isotope analysis. Optical gas analyzers provide high time resolution, high accuracy and precision, and can overcome limitations of more conventional instrumentation (such as mass spectrometry) relating to robustness, portability, cost of acquisition and ownership, and commercial availability. Thereby they enable new laboratory and field applications in industry and research that in the past were difficult or impossible to carry out. Progress in this field is still rapid, resulting in improved instrument capabilities and an ever-widening range of applications. Most instruments in the field are based upon spectral detection and, therefore, issues dealing with selectivity, sensitivity and stability play a key role in understanding the overall system performance. In atmospheric measurement applications selectivity is important, because the target gases are usually embedded in a mixture of background gases, which might interfere with the measurement. High resolution laser spectroscopy of the strong fundamental bands in the mid-infrared spectral region has proven to be well suited for highly selective measurements at reduced pressure.
