3D Magneto-Optical TrapLittle-MOT
High-performance integrated 3D MOT
A highly integrated 3D magneto-optical trap with ultimate vacuum better than 1×10-8 Pa. A built-in compound pump set and high-purity atom source sustain vacuum even without power; an anti-vibration, temperature-stable structure with factory pre-aligned optics lets it run standalone or integrate into your system via standard flanges.
Key Features
Highly integrated and reliable — so you spend time on physics, not on building systems.
Plug-and-Play
Power up the vacuum system, connect the laser via fiber and input the coil current to output a stable cold atom cloud.
High Flexibility
Independent compound pump set; usable standalone or integrated as a module via standard flanges, and portable with the vacuum system.
High Reliability
Compact integrated design reduces size, weight and power while improving robustness against vibration and temperature drift.
Compact Design
Integrates high-purity alkali vapor sources (Rb/Cs) with optimized pressure-gradient management for high atom numbers in short loading times.
Long-Life Vacuum
Advanced NEG and compact ion-pump technology hold better than 1×10-6 Pa for over 60 days without power as a standalone system.
Stable Optical Path
Anti-vibration, drift-resistant structure with all cooling, repumping and Raman beams factory pre-aligned for maximum power stability.
