basic information
(This is an excerpt from the Pound-Drever-Hall signal unit) This fully integrated PDH unit can achieve ultra-low noise error signals without the need for large RF generators or long, lossy RF delay lines. It combines a high-speed transimpedance amplifier, RF output signals driving EOM phase modulators, and lock-in detection within an RF-shielded enclosure to generate clear and clean PDH error signals. Optical detectors can be selected from silicon, InGaAs, and extended InGaAs, and full customization is available for fiber-coupled and free-space types.

| Pound Driver Hole Signal Unit | This fully integrated PDH unit can achieve ultra-low noise error signals without the need for large RF generators or long, lossy RF delay lines. It combines a high-speed transimpedance amplifier, RF output signals driving EOM phase modulators, and lock-in detection within an RF-shielded enclosure to generate clear and clean PDH error signals. |
| Fiber Noise Cancellation System | This product is a system designed to solve the problems encountered when sending stable light through noisy optical fibers by first performing accurate phase noise cancellation, allowing for the maintenance of a stable, narrow linewidth. It has been consolidated into a single unit to significantly reduce the installation footprint, making it usable with any stabilized laser system. The touchscreen interface controls an all-digital architecture that removes unwanted phase noise with just a button press. |
| Fiber Input/Output Laser Frequency Shifter | Our double-pass acousto-optic modulator design employs unwavering engineering to precisely tune the frequency of ultra-stable lasers between resonator modes. Whether there is a need to dynamically shift the frequency of the laser to cool and trap atoms or simply to correct for residual drift in the resonator, our laser frequency shifter enables a wide range of frequency shifts without optical realignment. |
