Ultra-short Optical Pulses
R. L. Fork, B. I. Greene, and C. V. Shank demonstrated, in 1981, the generation of ultra-short laser pulse using a ring-dye laser (or dye laser exploiting colliding pulse mode-locking). Such kind of laser is capable of generating laser pulses of ~ 0.1 ps duration.
The introduction of grating techniques and intra-cavity prismatic pulse compressors eventually resulted in the routine emission of femtosecond dye laser pulses.

Famous quotes containing the words optical and/or pulses:
“There is an optical illusion about every person we meet.”
—Ralph Waldo Emerson (1803–1882)
“I knew that I had seen, had seen at last
That girl my unremembering nights hold fast
Or else my dreams that fly
If I should rub an eye,
And yet in flying fling into my meat
A crazy juice that makes the pulses beat....”
—William Butler Yeats (1865–1939)
