Scientific paper

We describe recent progress toward developing optical frequency laser combs and tunable laser to the problem of more precise calibration of high dispersion astronomical spectra, thus permitting radial velocity determinations in the few cm/sec regime. We describe two programs in progress to calibrate both a cross dispersed echelle spectrograph with a laser comb and to calibrate a multiobject echelle spectrograph with a tunable laser.
