title: Field-test of a robust, portable, frequency-stable laser.
abstract: We operate a frequency-stable laser in a non-laboratory environment where the test platform is a passenger vehicle. We measure the acceleration experienced by the laser and actively correct for it to achieve a system acceleration sensitivity of Δf / f = 11(2) × 10(−12)/g, 6(2) × 10(−12)/g, and 4(1) × 10(−12)/g for accelerations in three orthogonal directions at 1 Hz. The acceleration spectrum and laser performance are evaluated with the vehicle both stationary and moving. The laser linewidth in the stationary vehicle with engine idling is 1.7(1) Hz.
