| description | In this thesis project, effort is concentrated on realizing a 480nm laser system which
allows one to excite atoms into Rydberg states with principal quantum number n>>1 for
quantum information processing experiment. A 960nm interference-stabilized external-cavity
diode laser (ECDL) has been realized. The output power of this laser is amplified
by a tapered amplifier to more than 1W. The output of this 960nm laser system is then
resonate in a bow-tie cavity resonator to enhance the fundamental beam circulating in
the nonlinear crystal to convert the 960nm light to 480nm light.
A microcontroller based PI (Proportional-Integral) temperature controller has been
realized. The controller enable one to have a constantly updating information of target
system temperature using LCD display. It also allows one to be able to store the value of
the temperature set point, PI constant or current set point in an external memory chip.
This controller is found to able to stabilize the target system temperature within +/- 0:001 degree Celsius. |
