Abstract

We report the operation of a bidirectional femtosecond pulsed ring optical parametric oscillator based on periodically poled lithium niobate, pumped alternately with nonsimultaneous pulses from a Ti:sapphire mode-locked laser. A beat note between the two counterpropagating beams attests to a gyro response without dead band. The sensitivity of the device to differential phase changes is demonstrated by measurement of the nonlinear index of lithium niobate.

Illustration of the OPO cavity pumped by the Ti:sapphire laser. The reflected and transmitted parts of the beam splitter, BS, are focused into the periodically poled LiNbO3 (PPLN) crystal via mirrors M1M2 and mirror M3, respectively. The difference between the two optical paths determines the crossing point of the signal pulses in the OPO cavity. The two output pulses are made to interfere on a detector, D, after an optical delay line brings them in coincidence. In exact alignment, BS and mirrors M1, M2, and M3 constitute an antiresonant ring, the output of which can be monitored with a CCD. Since the antiresonant ring has 100% reflection, an optical isolator, consisting of a Faraday rotator between two polarizers, is needed to protect the oscillator from the feedback.
