Lithium Spectroscopy

We use a vapor cell containing heated lithium metal and a small amount of inert buffer gas. Using saturated absorption spectroscopy, we stabilize the wavelength of the laser to one of the resonance features, giving the laser system long-term stability.

To avoid magnetic fields created by current in the heater wires, we use a counter-wrapped pattern (pictured below) outside a mu-metal shield around the vacuum chamber.
