High-precision wavelength calibration of astronomical spectrographs with laser frequency combs
M. T. Murphy, Th. Udem, R. Holzwarth +8
We describe a possible new technique for precise wavelength calibration of high-resolution astronomical spectrographs using femtosecond-pulsed mode-locked lasers controlled by stab…
