MZ Interferometer/AOM Imaging/Atomic Spectroscopy (Mu Young & Wen Yi)

Team Members: Kim Mu Young & Tan Wen Yi

Mach-Zehnder Interferometer

Aim: Carry out the MZ Interferometer experiment using a laser source. Observe constructive & destructive interference, and measure phase shift caused by different commonly-used optical elements

AOM Imaging

Context: Some experiments require the scanning of AOM frequencies. However, this results in the beam being deflected at slightly different angles. This can become an issue in ion trap systems where beam waists are very small (~10 um) and ion-beam alignment important.

Aim: We propose the use of a composite lens system on a movable platform, controlled by an actuator, so that a beam shift caused by a change in driving AOM frequency is automatically compensated for.

Atomic Spectroscopy

Aim: Observing Doppler-free spectrum of an iodine cell.

Material Required: The 739nm at Dzmitry lab is currently semi-available and thus may be used. Still need an iodine cell though. - Comment CK: if 780nm lasers are ok, we have probably many of them around. Will try to source an iodine cell. What line width are you aiming at?
