High efficiency and high power laser operation of highly-doped 2at.% crystalline Nd:YAG at 1.3microm is demonstrated in a diode-side pumped bounce amplifier configuration. A linearly polarized output power of 16.7W is obtained representing the highest power at 1.3microm achieved to date, to our knowledge, in a highly doped crystalline Nd:YAG laser. The system could deliver over 9W average output power in Q-switched operation with repetition rates from 20 - 160kHz. With quasi-continuous wave diode pumping 5.5mJ pulses at 100Hz repetition rate were achieved as well as 50ns pulses in Q-switched operation.
