The research on quantum computing and quantum memories both rely on an advanced experimental setup with a frequency stabilized laser at its core. Below is a simple figure of an overview of our experimental setup:
The most important equipment we use is listed below:
- Coherent 699-21 dye laser, pumped by an Nd laser for 606 nm (Praseodymium) or 580 nm (Europium)
- External cavity mounted diode lasers for 370 nm (Cerium) or other species.
- Stabilization and pulse shaping:
- Both the dye laser and the diode laser for 370 nm is frequency stabilized Pound-Drever-Hall locking to a stable high finesse cavity.
- The final linewidth of the dye laser is about 10 Hz, and for the diode laser about 1 kHz
- Accurate control of the phase and amplitude of the pulses is provided through a calibrated sequence of Acusto-Optic Modulators (AOMs)
- Oxford Instrumets bath cryostat with 8 T magnet
- Oxford Instruments flow cryostat
- Liquid Helium and Nitrogen supplied by in-house production facilities
- Experimental control system is custom built using LabView and Matlab programming
