title: Excitation of individual Raman Stokes lines in the visible regime using rectangular-shaped nanosecond optical pulses at 530 nm.
abstract: We demonstrate the selective excitation of individual Raman Stokes lines of up to the ninth order by pumping with rectangular-shaped optical pulses at 530 nm from a frequency-doubled adaptively pulse shaped fiber master oscillator power amplifier. We achieve extinction ratios of up to 15 dB between selected and adjacent Raman orders in a 1-km-long fiber.
