ABSTRACT:
A seeded electro-optically Q-switches laser includes a pulser for pulsing the Q-switch within the seeded laser. The Q-switch pulser includes a pulse-shaping network having a saturable core inductor connected in series with the flow of current to the Q-switch for causing the developed pulse voltage waveform in Q-switch to have an initially reduced rate of change to reduce unwanted Fourier frequency components of the seed optical radiation in the optical resonator of the slave laser, whereby enhanced single-mode operation of the slave laser is obtained with reduced seed power.
