Hall TW Hnsch for their contributions to the development of laserbased precision spectroscopy including the optical frequency comb technique Frequency Combs A revolution in measuring Nobel 2005 brPage 2br On Pulsed and Continuous wave lasers Conside Those light waves may be sent through a transparent medium as a laser beam or con tained within a fiber optic cable The conversion from high frequencyhigh speed electrical signals into light can occur in two general waysapplied directly to the power Division Multiplexing CO-OFDM. 1. Principle of orthogonal frequency-division multiplexing (OFDM). The principles of orthogonal frequency division multiplexing (OFDM) modulation have been in existence for several decades. However, in recent years these techniques have quickly moved out of textbooks and research laboratories and into practice in modern communications systems. The techniques are employed in data delivery systems over the phone line, digital radio and television, and wireless networking systems. Overview. Frequency Metrology. Measuring Frequency Gaps. Frequency Combs as Optical Synthesizers. Time Domain Applicatons . Stabilizing the Carrier Envelope Phase. Old and new Precision Spectroscopies. Acknowledgments. Zach . Berta (Harvard), the P.I. of HST program 12251, “The first characterization of a Super-Earth Atmosphere,” graciously agreed to our request to use GJ 1214 also for our engineering test, program 12325. Many persons, especially Merle Reinhart, Alan Welty, and William “Bill” Januszewski (STScI) helped plan the observations. Art Bradley (SSES) and Mike Wenz (GSFC) provided FGS data and analysis. .
