Within the scope of the second quantum revolution, laboratories and companies around the world focus on the search for the perfect quantum system suitable for applications of 'quantum technology 2.0'. Those applications range from quantum sensing, via quantum communication to quantum simulation and computing using Qubits opening up a vibrant research field to unveil materials with the perfect properties meeting the various requirements has evolved.
In this work, we discuss the optical setup and performance characteristics of commercially available Watt level, narrow linewidth Optical Parametric Oscillators (OPOs), tunable across the visible spectrum. We show several tuning mechanisms based on internal and external frequency stabilization and illustrate their deployment in quantum research applications. We also present a concept for compact laser systems, with narrower tunability, that can be tailored in wavelength to the desired application, as well as an extremely low-noise fiber amplifier platform, dedicated to quantum research. Experimental datasets from a selection of recently published studies on single-photon emitters of various types are presented.
