SolsTiS Rainbow brings together M Squared’s award-winning laser technologies into a single, easy-to-use platform providing hands-free automated access to light of any colour in the visible, near-ultraviolet and near-infrared wavebands. The advanced SolsTiS Rainbow features a fully-automated self-aligning, sealed, high-efficiency SolsTiS, a SolsTiS Doublet SHG cavity and a frequency mixing module, all capable of rapid and precise narrow-linewidth wavelength tuning in the range from 350 – 1100 nm. Furthermore, SolsTiS Rainbow is capable of user-defined high-speed, high-resolution stepped and continuous scanning over extended tuning ranges.
SolsTiS Rainbow is the only automated self-optimising laser system of its kind offering broad tunability across the visible, near-ultraviolet and near-infrared regions. Operation in each waveband, including wavelength selection, scanning and power optimisation, is entirely hands-free.
Broadest wavelength tuning available (350 – 1100 nm) from a single platform, incorporating continuous tuning from 350 – 700 nm and 700 – 1100 nm, making it ideal for a range of diverse applications in spectroscopy, spectral calibration, quantum and microscopy.
High-speed, high-resolution stepped and continuous scanning is available over extended tuning ranges with M Squared’s Dial-A-Wavelength and Terascan functionality as standard. Field proven in demanding space instrument calibration campaigns.
Ultra-narrow linewidth <200 kHz at 100 µs with a large coherence length (km). The SolsTiS Rainbow also has low amplitude and frequency noise at <0.1 % rms.
SolsTiS Rainbow features sealed cavities with easily replaceable desiccant module to ensure sustained performance over extended periods.
Highly efficient, self-aligning frequency mixing and resonant doubling of CW input light delivers >2 W peak at select VIS and UV wavelengths as well as >5 W peak at NIR wavelengths.
System footprint is well-suited to most optical tables and allows for easy integration. Sealed cavities enable gas purging and contaminant-free operation ensuring long crystal lifetimes. The Invar baseplate provides maximum optomechanical stability to normal environmental changes.
Easy-to-use remote operation is via a web-based control interface, which offers simple integration with third-party tools, such as LabVIEW.
