Abstract :
Capabilities of a high resolution diode laser spectrometer have been demonstrated by performing spectroscopy with thermal Ca and Sr atoms in an atomic beam and with laser cooled Ca atoms in a magneto optical trap. The minimum spectral linewidth of the observed fringes is as narrow as 1.5 kHz, allowing a small scale diode laser transfer frequency/length standard with a very low level of uncertainty
