We demonstrate a \SI{650}{\mW} \SI{243}{\nm} continuous-wave laser coupled to a linear optical enhancement cavity. The enhancement cavity can maintain $>$\SI{30}{\W} of intracavity power for \SI{1}{\hour} of continuous operation without…
Precision atomic spectroscopy is presently the work horse in quantum information technology, metrology, trace analysis and even for fundamental tests in physics. Stable lasers are inherent part of precision spectroscopy which in turn…
In this work, we investigate the steady-states of a fiber lasers mode-locked with a nonlinear amplifying loop-mirror that has an inherent amplitude noise-suppression mechanism. Due to the interaction of the sinusoidal transmission function…
Pound-Drever-Hall (PDH) laser frequency stabilization is a powerful technique widely used for building narrow-linewidth lasers. This technique is however ineffective in suppressing high-frequency (>100~kHz) laser phase noise detrimental for…
