LIGO laser splitter

LIGO laser splitter

Workers in Livingston, Louisiana are shown installing equipment used to split a powerful laser into two beams, each one traveling down a different arm of the LIGO observatory. The beams bounce off a mirror at the end of each arm and return to the center exactly out of phase, cancelling out the energies of each. (Credit: LIGO Scientific Collaboration)
