Abstract :
Long-term single-frequency stabilisation of an external-cavity semiconductor laser has been demonstrated using a multisegment composite-cavity configuration and an automatic frequency control loop with feedback to the external cavity. Mode-hopping free single-longitudinal-mode oscillation with a linewidth of about 200 kHz and a frequency shift within 28 MHz has been observed over 24 h.
