High-repetition-rate laser pulse amplifiers are desirable for investigations of weak signals because of the ability to use ultrasensitive lock-in detection. We have developed a new oscillator and amplifier capable of providing 10 MW of power at repetition rates in excess of 1 kHz. By focusing this pulse we have obtained the white-light continuum with as little as 250 nJ of energy.
