In the domain of quantum sensors, compact laser systems with extremely narrow linewidth and precise control over emission frequency and output power are indispensable components. To alleviate the user's workload, expedite operational processes, and reduce the level of expertise required, an automated adjustment of various actuators becomes essential. As part of an integrated solution, we introduce a high-power, narrow-linewidth laser module, complemented by a frequency-tunable reference module, both operating at a wavelength of 767 nm. While the laser module features an active stabilization of the optical resonator length and enables mode-hop-free tuning of the optical emission frequency, the frequency reference module facilitates an accelerated lock-acquisition. Together, these advancements pave the way for more accessible and efficient quantum technology applications.
