729nm Single Frequency Fiber Laser
Product Description:
Connet 729nm Single Frequency Fiber Laser is based on the technology of the mature 1.9um and 1.1um 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 729nm 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-729-B has the narrower linewidth and the lower
phase noise and frequency noise, and better beam quality.
Applications:
• Atom Cooling
• Rydberg Inspire
• Cold Atomic Physics
• Atomic Clock
• Quantum Measurement
Features:
• Ultra-narrow linewidth<50kHz
• Low noise
• Output Power>20mW
• Linear Polarization Output, High PER
