Abstract:
A method for amplifying a laser pulse, comprising:providing at least one oscillator pulse from an ultrashort-pulse, mode-locked oscillator; stretching said at least one oscillator pulse to produce at least one stretched pulse; directing said at least one stretched pulse onto at least one nonlinear crystal comprising bulk crystalline material; providing at least one pump pulse from a pump laser system, wherein said at least one pump pulses comprises a pulse duration within a range from 1 to 15 times the pulse duration of said at least one stretched pulse; and directing said at least one pump pulse onto said at least one nonlinear crystal, wherein said at least one stretched pulse and said at least one pump pulse are operatively directed at said at least one nonlinear crystal and operatively phase matched in said at least one nonlinear crystal to produce at least one amplified output signal pulse.
