The properties of Rydberg Atoms allow ultracold samples of highly excited atoms’ to interact with each other which can lead to a blockade effect that would eventually be useful in building quantum computers. A diode laser system is developed for use of populating Rydberg states of rubidium atoms in a magneto-optical trap. My first task was to learn how to properly use Laser and spectroscopy. Then I will work on building and testing circuits specifically designed and printed on the PCB board based on conventional lock-in techniques, which will greatly improve the stability of frequency to sub-megahertz level. The lock-in box design includes integrated lock-in amplifier, local oscillator, ramp generator, and piezo driver.
