摘要:
A mode locked laser supplies a high repetition seed pulse train along a seed beam path to a pulse picker having at least one polarizer. A Faraday rotator in optical communication with the seed beam rotates the polarization of the seed beam by about 45°. A double pass acousto optical modulator (AOM) receives the seed beam propagating through the Faraday rotator and diffracts the seed beam into a first order first pass beam and a zero order first pass beam. A reflector returns the first pass first order beam into the acousto optical modulator for a second pass. The modulator diffract the beam into a zero order second pass beam and a first order second pass diffracted beam, the first order second pass beam propagating on the substantially same path as the incoming seed beam but in the opposite direction.
