Abstract
An Nd:YAG laser pumped by an array of diode laser bars. The diode laser bars are driven by high frequency pulsed DC and switched so that the bars may be driven in any desirable combination, but not all bars are driven at the same time. Switching between sequential bars must provide an overlap to accommodate the lag between the optical output of the main laser cavity and the input pulse to the diode bar. Althrough the diode bars operate uncooled at a low duty cycle, the YAG output is a continuous wave.
