An ultrafast light gate

  title={An ultrafast light gate},
  author={M. Duguay and J. Hansen},
A device has been built which is capable of gating light on and off on the picosecond time scale. The gate is built in much the same fashion as traditional Kerr cells, the difference lying in the use of powerful optical pulses rather than electrical pulses to induce a birefringence in various liquids. In the experiment, powerful light pulses from a mode-locked Nd:glass laser, ∼5 psec in duration (wavelength 1.06µ), are used to induce a birefringence in a number of liquids including CS… Expand
