Subsystem ‐ Laser Cooling and Detection

Laser Cooling and Detection Subsystem:

1. ECDL - Extended Cavity Diode laser
2. Isolator - Optical isolator and cylindrical lens pair
3. Telescope - reduces laser beam waist
4. Rb SAS - stabilizes the laser frequency using Saturation Absorption Spectroscopy
5. Double Pass (focal length 50mm) - modulates laser intensity and frequency
6. Fiber coupler - monitor wavelength with wavemeter
