Newport's Spectra-Physics division has introduced the Iris optical parametric oscillator (OPO), a new, tunable, ultrafast laser source for advanced imaging and spectroscopy applications.

The manufacturers state that the Iris OPO features the widest gap-free ultrafast tuning range in the industry, from ultraviolet to infrared (340-2500nm), along with the highest power in the UV and visible. The OPO is fully automated, and tuning accross the range can be computer controlled without adjustment or changes of optics.

The Iris OPO has multiple output ports for simultaneous UV, visible and infrared output, making it ideal for applications that require multiple wavelengths, such as coherent anti-Stokes Raman scattering (CARS) imaging. The OPO delivers more than 1W of average power at wavelengths of 340-520nm, and greater than 400mW at 490-750nm. Additionally, the new OPO provides adjustable pulse widths (80-350fs). Optimised for high stability, the OPO is insensitive to ambient temperature change.
