Light Sound Handling Products - Stable Laser Systems Cavity Housing Series
To ensure the stability of the cavity and minimize frequency drift, it is important to properly select the vacuum housing. SLS engineers have conducted years of finite element modeling and experimental validation of acceleration sensitivity, adapting the design of the cavity, mount points, and housing to a wide range of shapes. - Exceptional temperature stability enables low frequency drift across a wide operating range - Carefully designed mounting structure to minimize vibration sensitivity - Custom temperature stabilization suitable for laboratory or field experiments

basic information
(Excerpt from Cylinder & Notch Cavity Housing) We use a meticulously modeled mount support to minimize acceleration sensitivity, along with a vacuum housing designed for rigidity, low thermal expansion, and vibration damping. Our pair of cavities and housings achieves remarkable low drift over a wide temperature range. For linewidths below 100Hz, we recommend the notch cavity over the cylindrical cavity in terms of acceleration sensitivity and performance.

| Cylindrical & Notch Cavity Housing | We use meticulously modeled mount supports to minimize acceleration sensitivity and vacuum housings designed for rigidity, low thermal expansion, and vibration damping. Our cavity and housing pair achieves significant low drift over a wide temperature range. For linewidths below 100Hz, we recommend notched cavities over cylindrical cavities in terms of acceleration sensitivity and performance. |
| Mid-plane cavity housing | Understanding of finite element modeling of temperature effects in various combinations of cavities and housings, along with skills in their construction, allows us to leverage the unique flexibility of vertical mounting of mid-plane cavities. From two-stage temperature stabilization to fiber coupling, transport, and sealed vacuum housings, we can create the solutions you need in a fraction of the time it has taken so far. |
| Multi-stage cavity housing | Multiple insulated nesting shells surround the optical resonator, enveloping it in a highly isothermal environment. Due to the thermal time constant being on the order of several days, the cavity is unaffected by temperature fluctuations in the laboratory on the scale of hours or days. Additionally, careful shell design ensures that spurious blackbody radiation does not directly impact the cavity. Our multi-stage cavity vacuum container provides optimal performance for your optical atomic clock and spectroscopy research. |
