Subsystem ‐ 2D Magneto Optical Trap (MOT)

2D Magneto Optical Trap (MOT) subsystem:

1. ECDL - Extended Cavity Diode laser
   1. Isolator - Optical isolator and cylindrical lens pair
   2. Telescope - reduces laser beam waist
2. SAS - stabilizes laser frequency using Saturation Absorption Spectroscopy
3. Double Pass (focal length 50mm) - modulates laser intensity and frequency
4. Fiber coupler - monitor wavelength with wavemeter
5. MOT subassembly
   1. MOT Branch X - PBS splits off power from main branch and directs through quarter waveplates and retro-reflection
   2. MOT Branch Y - Next branch directs light orthogonally to first branch
   3. MOT Branch Z - Final branch cools and confines atoms in 3rd dimension
   4. Permanent Magnet holders - Creates anti-Helmholtz field at the center of the MOT (MISSING)
