Two-colour high-purity Einstein-Podolsky-Rosen photonic state
Tulio Brito Brasil, Valeriy Novikov, Hugo Kerdoncuff +2
Entanglement is the backbone of quantum information science and its applications. Entangled states of light are necessary for distributed quantum protocols, quantum sensing and qua…
Quantum frequency conversion of vacuum squeezed light to bright tunable blue squeezed light and higher-order spatial modes
Hugo Kerdoncuf, Jesper B. Christensen, Mikael Lassen
Quantum frequency conversion, the process of shifting the frequency of an optical quantum state while preserving quantum coherence, can be used to produce non-classical light at ot…
Quantum-Enhanced continuous-wave stimulated Raman spectroscopy
R. B. Andrade, H. Kerdoncuff, K. Berg-Sørensen +3
Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity, resolution and speed. However, sensitivity and speed…
Cavity-enhanced sum-frequency generation of blue light with near-unity conversion efficiency
Hugo Kerdoncuff, Jesper B. Christensen, Túlio B. Brasil +4
We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-reso…
Continuous-wave coherent Raman spectroscopy for improving the accuracy of Raman shifts
Hugo Kerdoncuff, Mikael Lassen, Jan C. Petersen
Raman spectroscopy is an appealing technique that probes molecular vibrations in a wide variety of materials with virtually no sample preparation. However, accurate and reliable Ra…
Simple and robust speckle detection method for fire and heat detection in harsh environments
Charles N. Christensen, Yevgen Zainchkovskyy, Salvador Barrera-Figueroa +8
Standard laser based fire detection systems are often based on measuring variation of optical signal amplitude. However, mechanical noise interference and loss from dust and steam…
