Mw. Phillips et al., FREQUENCY COMB GENERATION AND PULSED OPERATION IN A ND-YLF LASER WITHFREQUENCY-SHIFTED FEEDBACK, Optics communications, 100(5-6), 1993, pp. 473-478
An injection-seeded Nd: YLF laser incorporating frequency shifted feed
back generates a frequency comb with a 140 GHz bandwidth and a tunable
frequency spacing. Near bandwidth-limited pulses of 31 ps duration ha
ve been produced in the seeded laser by matching the frequency shift t
o a multiple of the cavity roundtrip frequency.
