852nm Single Frequency Fiber Laser
Product Description:
Connet 852nm Single Frequency Fiber Laser is based on the technology of the mature 1.9um and 1.5um distributed feedback Bragg grating (DFB) type low-noise single frequency fiber lasers. Connet has the independent intellectual property rights on this technology. The nonlinear frequency conversion technology is adopted to achieve the stable 852nm single frequency laser output with the linear polarization, single longitudinal mode, and the ultra-narrow linewidth. Comparing with the traditional TA type semiconductor laser, CoSF-852-B has the narrower linewidth and the lower
phase noise and frequency noise, and better beam quality.
Applications:
• Cesium Atom Cooling
• Cesium Atomic Clock
• Rydberg Inspire
• Quantum Measurement
• Cold Atomic Physics
Features:
• Single Frequency, Single Longitudinal Mode, Linear Polarization Output
• Narrow Linewidth (<20kHz）
• Mode-hop Free
• Low Noise
• Output Power in Optical Fiber Type: 200mW
