  • High efficiency laser operation of 2 at.% doped ...

    2006-2-6 · High efficiency and high power operation of highly-doped 2 at.% crystalline Nd:YAG is demonstrated in a diode-side pumped bounce amplifier configuration. A linearly-polarized output power of 46.1W is obtained with 101W diode pumping representing the highest power achieved to date, to our knowledge, in a highly doped crystalline Nd:YAG laser.
