摘要
Diode laser linewidths have been reduced by a factor of up to 20000 using the technique of resonant optical feedback. In this method, the laser frequency also locks optically to a confocal cavity, greatly improving the passive frequency stability. For the first time, such an optically narrowed diode laser has been used to obtain high-resolution Doppler-free spectra of the D2 line of85Rb and87Rb at 780 nm. © 1990 Taylor & Francis Ltd.
