An ultra-short pulsed laser system comprises an optical combiner, optical amplifier, optical pulse compressor, and optical separator. The optical combiner is configured to combine a primary optical pulse with a secondary optical signal to generate a combined optical signal. The primary optical pulse...http://www.google.se/patents/US8125704?utm_source=gb-gplus-sharePatent US8125704 - Systems and methods for controlling a pulsed laser by combining laser signals
