C. Svelto et al., POUND-DREVER FREQUENCY-STABILIZED YB-ER-GLASS LASER AGAINST C2H2 MOLECULE AT 1.534097-MU-M, Electronics Letters, 34(5), 1998, pp. 461-462
The Pound-Drever-Hall technique has been successfully used to stabilis
e a diode-pumped bulk Yb-Er:glass laser against the P(15) re-vibration
al line of the acetylene molecule. Absorption and dispersion-like spec
tra of the 1.534097 mu m molecular transition have been measured. The
stabilised laser shows a robust and repeatable locking regime, with a
root mean square frequency stability, measured over a 24h period, of b
etter than 200kHz.
