Simplified laser oscillator-amplifier system

A simplified laser oscillator-amplifier system comprising:

• a laser oscillator having a first gain medium and a spectrum control mechanism, said laser oscillator produces a seed pulse when said gain medium is excited with a pump pulse;
• a laser amplifier having a second gain medium and a Q-switch, said laser amplifier has a cavity length of approximately 5 to 10 cm and amplifies said seed pulse to generate a short amplified pulse having a pulse duration of approximately 1 ns to 5 ns;
• and
• said pump pulse of radiation split to pump both said laser oscillator and said laser amplifier;
• wherein said laser oscillator-amplifier system produces a single amplified laser pulse with predetermined pulse energy and spectrum bandwidth.
