Abstract
We report to our knowledge the highest to date quasi-CW output power, 600 W and pulse energy, >1 J, for an InGaAs diode-pumped Yb:YAG laser. In separate preliminary results, we have also obtained 225 W of avera ge output power under true CW diode pumping. This performance was obta ined using a laser head designed to be part of a master oscillator pow er amplifier (MOPA) operating at 3 kW. We summarize why the diode-pump ed Yb:YAG crystal laser is ideal for scaling to high average powers an d the different approaches being pursued. We also report our latest re sults for side-pumped rod devices.
