Reliable and tunable ultraviolet (UV) laser sources are increasingly important for applications in spectroscopy and precision metrology, yet many UV wavelengths remain difficult to access efficiently.
We present a set of UV laser systems that employ cascaded sum-frequency-generation (SFG) stages in nonlinear crystals using different phase matching schemes.
The fundamental light is provided by Diode, VECSEL and Ti:Sa lasers.
The SFG stages are implemented in both single-pass and cavity-enhanced configurations, including one system employing an elliptical cavity mode.
The resulting systems deliver stable, narrowband radiation across multiple regions of the UV spectrum, from 185 nm to 310 nm, demonstrating a versatile and scalable platform for advanced UV laser generation.
