The candidate will join the OHMS team of the Time-Frequency department of FEMTO-ST. The candidate must have a major interest in high-precision measurements, present skills in optics, electronics and instrumentation. The knowledge of mechanical design and fundamental physics is a real asset. He or she will evolve within a team made up of researchers, engineers and technicians, and will have the support of the electronic, mechanical and IT departments of the FEMTO-ST Institute and the OSCILLATOR-IMP infrastructure of excellence, dedicated to time & frequency metrology. The candidate will present their work at international conferences and will aim to have their work published in international journals.
The subject is : Development of a stabilized laser on a sub-Kelvin Fabry-Perot cavity
Abstract : Ultra-stable lasers have a central role in numerous scientific experiments for high precision measurements: atomic spectroscopy, diffusion of time & frequency signals by optical fiber, detection of gravitational waves and dark matter research. The performances are currently reaching fractional frequency stabilities below 10-16 at 1 second of integration. However, it is still insufficient for many applications including fundamental physics tests and optical atomic clocks.[...]
Prerequisites : PhD in Physics
Desired skills: Optical frequency metrology, Gaussian optics in free-space, Analog, digital and radio-frequency electronics, Control theory and locking/feedback techniques, Instrumentation, Cryogenic and ultra-high vacuum, Analysis and interpretation of noise and sources of noises
Contract duration : 1 year - Salary : approximately €2300 net
