Experiences with our cryogenic systems, from quantum optics to metrology

"Our custom cryostat based on OptiDry 250 was developed in close collaboration with My Cryo Firm, and their support has been excellent throughout the process. Their responsiveness and willingness to refine details made the project very smooth.”

OptiDry 250 with 1 K option and integrated 2 T magnet

“For nearly two decades, the Time-Frequency Department at FEMTO-ST has developed ultra-stable oscillators based on cryogenic sapphire resonators, achieving frequency stability better than 3 × 10⁻¹⁵. In collaboration with My Cryo Firm, the department launched ULISS-2G in 2013, a compact, low-power, autonomous oscillator designed for National Metrology Institutes. Now available through FEMTO Engineering, ULISS-2G continues to evolve, delivering improved performance and reliability."

Custom development

“Over the past five years, our research team at C2N has used three OptiDry 250 systems with 7 T magnets and custom designs for cavity polariton studies. Their excellent thermal and mechanical stability is crucial for our work on polariton condensates and synthetic photonic lattices. The reliability and customization of these low-temperature optical setups make them essential to our research. We also value the expertise and support of the My Cryo Firm team and highly recommend their solutions for such applications.”

"The OptiDry 250’s thermal stability below 3 K is ideal for our rare-earth-doped crystal experiments, ensuring the low-noise environment needed for coherent optical transitions. The precise customisations and robust design make it a reliable tool for our quantum photonics
research."

“Working with My Cryo Firm on our OptiDry 7 T system with a 1 K option has been an excellent experience. Their engineers understood our requirements for ultra-low-temperature quantum optics, particularly single-molecule fluorescence experiments. They supported us throughout the design process, ensuring thermal stability at 1 K and seamless integration into our cryo-microscopy setup. The system has delivered outstanding performance for high-resolution spectral measurements.”

"We installed a customized OptiDry cryostat in our lab in March 2024. It is equipped with 72 DC lines and six RF cables, and it can deliver the high currents needed to drive a superconducting magnet. Since installation, it has been running flawlessly. We are very pleased with both the design of the system and the support provided by My Cryo Firm: the team is always willing to help and comes on site whenever needed. I can only recommend this French gem."
