Abstract
Section titled āAbstractāDiamond Raman lasers (DRLs) are novel high power, narrow linewidth sources with output wavelengths challenging to generate by other means, such as the 589 nm guide star line. While DRLs have been demonstrated to operate single-frequency at high powers for short durations, locking to a frequency reference has not yet been achieved. Here, we report an intracavity frequency doubled, 589 nm DRL stabilised to a wavemeter. Frequency fluctuations of +/- 75 MHz of the frequency setpoint were obtain over a 15 minute period. The effective and intrinsic linewidths were also measured, yielding 8 MHz and <900 Hz (resolution limited) respectively.
