AbstractNegative feedback controlled mode locking techinque was applied on a phosphate Nd:glass oscillator. The pulse intensity in the cavity was kept at a low level to avoidself-phase modulation and other nonlinear effects.The building time of mode lockedpulse was prolonged to approximately 10 micro-seconds. As a result, a neartransform-limited picosecond laser pulse was obtained.It provided a good light seed forchirped pulse aplification system.Figure 2 is the scheme of the negative feedback controlled circuit.This circuit put ahigh voltage pulse, which is nearly propotional to the light pulse intensity in the cavity, onthe crystal of Pockels cell to change the loss of the cavity.A single pulse was dumped from the cavity by pulse selector which consisted apolarizer, a Pockels cell and the relative circuit.The pulse duration and the bandwidth of the output picosecond pulse were measured.The result are shown in Figure 6 and Figure 7.
