Laser Frequency Stabilization With Pound-Drever-Hall Technique
… for a continuous-wave diode laser. Using the Pound-Drever-Hall technique, the system can significantly reduce the linewidth of an input laser with an un-stabilized linewidth. It uses a high-finesse Fabry-Perot cavity, which is mechanically and thermally isolated, as a frequency reference to …

A Narrow-Linewidth Laser at 1550 nm Using the Pound-Drever-Hall Stabilization Technique
… system for infrared fiber lasers. Using the Pound-Drever-Hall technique, the system significantly reduces the linewidth of an input laser with an un-stabilized linewidth of 2 kHz. It uses a high-finesse Fabry-Perot cavity, which is mechanically and thermally isolated, as a frequency reference …

Continuous detuning of an optical cavity with a Universally Tunable Modulator
… to lock an optical cavity on resonance using the Pound- Drever-Hall technique. It is also possible to lock a cavity at a single detuned length using an amplitude modulated laser beam. However, there are many interesting applications, that would benefit from the use of a Universally Tunable …

Implementation of side-fringe locking in an SHG cavity
… is described and implemented. The usual method, Pound-Drever-Hall locking, is prone to long-term power fluctuations from power variations in the incident laser. When using the second harmonic field for squeezing, these power fluctuations need to be stabilized with an additional control loop …

Frequency stabilization for a 486nm dye-ring laser
… I aligned the cavity and then observed a Pound-Drever-Hall error signal. This error signal will be fed back into the laser to stabilize the frequency. It is anticipated that when the electronics to utilize the error signals are completed, the laser frequency will be stabilized to a hundred …

Integrated silicon photonic circuit simulation
… of complicated systems such as WDM links and Pound-Drever-Hall loops. This will allow designers to unify our photonic device designing and modeling environment with circuit and system level design, giving us greater insight on the trade-offs that take place between the two realms.

Towards Large-Scale Integrated Electronic-Photonic Systems
… for the past decade. However, there remain some challenges in integrated photonic systems including lack of fast, high performance, and mature electronic circuitries to control the photonic devices and perform fast, reliable, and efficient processing and measurement. Thanks to the silicon platform …

Trapping and Cooling of Bosonic Strontium for a Long-Baseline Atomic Interferometer Observatory and Network (AION)
… 461 nm MOT for initial cooling and trapping. A Pound-Drever-Hall stabilised Ti:Sapphire laser, narrowed to sub-kilohertz linewidth at 689 nm, facilitates further cooling in a three-dimensional 689 nm MOT addressing the narrow inter-combination line. Broadband to narrowband sequences enable the …

Er:YAG Lasers for Methane and Wind Sensing
… The laser is frequency stabilised using the Pound-Drever-Hall (PDH) frequency stabilisation method to “lock” two low-power diode lasers to the Er:YAG resonator to produce reliably injectionseeded pulses. The laser designed and built in this thesis produces two free-running pulses each with …
