Abstract

A simple LD-end-pumped, passively mode-lockedNd:YVO4 ring laser with bidirectional outputs was demonstrated,and the gyroscopic properties of the ring laser was studied. Thelaser was continuous wave mode-locked by use of a semiconductorsaturable absorber mirror (SESAM), and both clockwise andcounter-clockwise outputs are stable laser pulse trains with pulseduration of 64 ps. The continuous wave mode-locking was obtainedunder pump power as low as 540 mW. The average output power is50 mW for the counter-clockwise laser and 52mW for the clockwiselaser under pump power of 1378 mW. The whole slope efficiency ofthe ring laser is about 9.4%. The two output pulse trains of thering laser were combined to study its gyroscopic properties. Thebeat frequency of the pulsed solid-state laser gyro versus therotation rates follows the Sagnac formula. The laser gyro has alarge dead band of 6-8 dec/s, which was believed to be caused bythe long pulse duration and the colliding of the opposite pulseson the SESAM.
