Phase locked laser system

A complete system based on two phase-locked SolsTiS lasers. The high power and extremely low phase noise light provides an excellent platform for atom interferometry.

  4. SolsTiS Phase Locked

The phase locked SolsTiS system is primarily designed for use in atom interferometry and quantum computing where Raman transitions are commonly used, although we can tailor the setup to other applications. The system provides extremely low phase noise and high output powers. Full control over the system is provided through our easy to use Ice Bloc user interface.

  • 20 dB polarization extinction ratio for each fibre output
  • 50 dB on/off extinction ratio for each fibre output
  • < 1 μs switching time for each fibre output
  • Monitor photodiodes on the input to each fibre
LOW PHASE NOISE
In the Raman configuration, the Allan deviation of phase between lasers locked at 6.834 GHz offset frequency is < 11 mrad for averaging times 10-100 ms. This is sufficient for measuring acceleration at ~ 1 x 10-9 g/√Hz.

FREQUENCY CHIRP
Phase continuous frequency chirp of laser Raman frequency for tracking Doppler shifts for accelerations of up to 2 g. Both the phase lock offset frequency and the chirp rate are reconfigurable through an Ice Bloc user interface.
LONG TERM FREQUENCY STABILITY
Both SolsTiS lasers are referenced to the same rubidium reference cell, giving a long term frequency instability of < 50 kHz.
