A compact, multi-pixel parametric light source
The features of a compact, single pass, multi-pixel optical parametric
generator are discussed. Several hundreds of independent high spatial-quality
tunable ultrashort pulses were produced by pumping a bulk lithium triborate
crystal with an array of tightly focussed intense beams. The array of beams was
produced by shining a microlenses array with a large pump beam. Overall
conversion efficiency to signal and idler up to 30% of the pump beam has been
reported. Shot-to-shot energy fluctuation down to 3% was achieved for the
generated radiation.Comment: 11 pages, 6 figures, submitted to "Optics Communications
