High Quantum Efficiency (HQE) Balanced Detector Component

High Quantum Efficiency (HQE) Balanced Detector ComponentNoisy Labs' high quantum efficiency balanced detectors are engineered for precision measurements of squeezed states of light and weak signals carried by cw laser light. These systems exhibit very low electronic dark noise, providing a high dark noise clearance of more than 20 dB with maximally 20 mW of local oscillator power in the MHz frequency range. With a high quantum efficiency of >95% (and >99% by design), users can directly detect at least 10

tailored to customer specifications

table-top system (footprint 41 cm x 61 cm) designed for the generation of continuous-wave squeezed vacuum states at either 1550 nm or 1064 nm

With a high quantum efficiency of >95% (and >99% by design)

Our general purpose balanced detectors are available at 1064 nm

ensuring excellent beam characteristics

This enables extended measurement periods with stable squeezed quantum noise

including entangled beam generation or photon pair sources

resulting in a high dark noise clearance of more than 20 dB with maximally 20 mW of local oscillator power in the MHz frequency range
