Efficient narrow-linewidth volume-Bragg grating-locked Nd:fiber laser.
A neodymium doped microstructured large mode area fiber is frequency locked with a volume Bragg grating. This configuration is compared with a conventional fiber laser setup. A high efficiency (51% slope), stable output and a drastically narrowed linewidth (<0.07nm) are achieved.
