The dynamics of a mode locked and frequency doubled laser

The theory for the transient build-up of mode locked pulses in a modelocked and frequency-doubled laser is presented. The time required for the modelocked pulsewidth to reach a steady-state value is computed. It is found that steadystate is reached faster in the presence of internal frequency doubling because of the broadenhg effect of the doubling crystal. The effects of different conversion efficiencies and modulation depths on the mode-locked pulsewidth are investigated and the results are graphically presente
