Windeler and John Hall}, title = {Direct rf to optical frequency measurements with a femtosecond laser comb}, abstract = {By spanning an optical octave ( 300 THz) with a broadened femtosecond laser frequency comb, we directly measure the frequencies of optical standards at 1064/532 nm, 633 nm and 778 nm in terms of the microwave frequency that controls the comb spacing. This microwave frequency can be linked directly to the cesium standard.}, year = {2000}, journal = {IEEE Transactions on Instrumentation and Measurement}, volume = {50}, pages = {552-555}, month = {2000-04}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=00918189}, note = {JILA Pub. 6591}, }
