High-Precision Photon Counting for Quantum Research

Intuitive setup, live FWHM analysis, and in-measurement adjustments

Accurate timing is essential when investigating quantum dots, NV centers, or entangled photon sources. A powerful combination of software and hardware enables precise g²(τ), lifetime, and coincidence measurements across a wide range of quantum optics experiments.

A powerful integration of software and hardware:

UniHarp DAQ Software
Offers an intuitive interface for photon correlation experiments, with real-time FWHM analysis and parameter adjustments during acquisition. Ideal for streamlining setup and analysis in g²(τ) and TCSPC applications.

Precise and Versatile Time Tagging and TCSPC Unit PicoHarp 330
A compact time tagger with 1 ps resolution, 680 ps dead time, and TTTR mode. Well-suited for HBT configurations and photon statistics analysis where space and channel count are limited.

High-Resolution Multichannel Time Tagging and TCSPC Unit HydraHarp 500
Designed for demanding quantum experiments, it features up to 16 input channels, low dead time, and synchronization options such as White Rabbit. A flexible solution for multi-channel correlation and time-tagging setups.

Why Should You Use The 3-Color Gain-Switched Picosecond Laser Prima

Turning Vision into Results

A recent study by researchers at Mitsubishi Electric Research Laboratories (MERL) shows that it can. Using a technique called Doppler Single-Photon Lidar (SPL), they were able to simultaneously estimate distance and radial velocity with remarkable precision. Their setup worked even at high frame rates and in extremely low signal conditions, opening up new possibilities for motion-aware 3D imaging.

Behind this success was a careful choice of hardware. The team needed a laser source that could meet both the precision requirements and the flexibility needed for demanding SPL experiments. That's why they chose Prima.

Joshua Rapp, Principal Research Scientist at Mitsubishi Electric Research Laboratories and one of the authors of the recent study on Doppler single-photon lidar says:

 "We originally chose the Prima laser because it had one of the highest repetition rates for pulsed lasers that we could find."
