| Abstract(in English) | A technique of feedback controlled mode-locking (FCM) is an useful method to enhance the effect of colliding pulse mode-locking (CPM) and to reduce the laser pulse width in a flash-pumped Nd:YAG laser. Generally, the pulse repetition rate of a passively mode-locked laser is determined by the cavity length. As a method of increasing the mode-locking frequency, we set the saturable absorber on 1/4 or 1/6 of the cavity length. In these case, the multiple mode-locking frequency is 4 Δ, 6 Δ respectively. By joint operation of CPM and FCM, the pulse train was stretched up to 1200ns, pulse repetition rate was increased up to 750MHz, and the pulsewidth was shortened down to 2.6ps in sech^2 shape, while the Pulse energy was still 5 μ J. |
