MOGLabs, a developer of laser control, measurement, and photonics instrumentation solutions, offers the PDA030 Amplified Photodetector, a high-speed, low-noise detection system designed for demanding optical measurement and laser stabilization applications. The detector is engineered to provide high sensitivity, broad spectral response, and low-noise signal acquisition for research laboratories and advanced photonics environments.

The PDA030 is specifically developed for applications that require precise optical signal detection, including Pound-Drever-Hall (PDH) optical cavity locking, laser frequency stabilization, spectroscopy, and optical diagnostics. These applications demand highly stable photodetection systems capable of accurately capturing weak optical signals while minimizing electronic noise that can degrade measurement performance.

At the heart of the system is a high-performance silicon photodetector coupled with an integrated amplification stage. The detector provides a measured bandwidth exceeding 30 MHz, enabling fast signal acquisition for dynamic optical measurements and high-speed feedback control systems. Its broad spectral response extends from 300 nm to 1060 nm, allowing operation across ultraviolet, visible, and near-infrared wavelengths commonly used in laser and spectroscopy applications.

The PDA030 delivers high detection efficiency through a quantum efficiency of approximately 0.64 at 900 nm, enabling effective conversion of incident optical signals into electrical outputs. Combined with a low noise-equivalent power specification, the detector is capable of measuring extremely weak optical signals while maintaining a high signal-to-noise ratio. These characteristics are particularly valuable in precision laser experiments and cavity-locking systems where measurement sensitivity directly affects overall system stability.

To improve measurement reliability, MOGLabs has incorporated an electrically isolated 50-ohm BNC output connector that helps eliminate ground-loop effects commonly encountered in laboratory optical setups. Ground loops can introduce unwanted electrical interference and noise, particularly in high-sensitivity photonics experiments. The isolated output architecture helps maintain clean signal acquisition and stable operation in complex optical laboratories.

The detector is housed in a compact mechanical package designed for straightforward integration into optical systems. It features an SM1-threaded optical interface, allowing users to easily attach optical tubes, lenses, filters, and other standard optical components. Multiple threaded mounting points further simplify installation on optical tables and experimental platforms. Power is supplied through a standard M8 connector compatible with MOGLabs control systems as well as selected third-party laboratory power supplies. This enables convenient integration into existing experimental setups while supporting a wide operating voltage range.

The PDA030 complements MOGLabs’ broader portfolio of laser measurement and stabilization products, which includes compact wavemeters, Fizeau wavemeters, differential photodetectors, and laser control electronics. Together, these technologies support applications in quantum optics, atomic physics, laser spectroscopy, optical metrology, laser cooling, and photonics research. By combining low-noise performance, high bandwidth, broad spectral sensitivity, and compact integration, the PDA030 Amplified Photodetector provides researchers and engineers with a versatile solution for precision optical detection and advanced laser control applications.
