Abstract
The output beam profile of a Nd:YAG diode-pumped ceramic regenerative amplifier depends heavily on amplified spontaneous emission (ASE) and amplification competition. A careful pump geometry arrangement is required in a highgain regenerative amplifier to achieve the beam profile that corresponds to the TEM00 mode of the amplifier cavity.
