Sa. Guskov et al., 2ND-HARMONIC GENERATION AROUND 0.53-MU-M OF SEEDED YB FIBER SYSTEM INPERIODICALLY-POLED LITHIUM-NIOBATE, Electronics Letters, 34(14), 1998, pp. 1419-1420
Fibre-integrated, seeded, high-power Yb-doped fibre amplifiers have be
en used in combination with periodically-poled lithium niobate crystal
s in simple experimental configurations to give second harmonic genera
tion to the visible both in CW and pulsed formats with conversion effi
ciencies as high as 41% in compact configurations.
