Scan Series Nanosecond OPO Family

The Spectra-Physics® Scan series OPO family is German engineered by our partner firm GWU to offer superior performance in a compact, rugged package. With three series to choose from—the entry-level basiScan, versatile versaScan and premier premiScan—the Scan series will meet a wide range of budgets and requirements.

The Scan series OPOs offer the lowest pump thresholds on the market making them the most efficient and robust OPOs available. Lower pump fluences result in longer lifetimes for the internal components, especially the BBO crystal. And, the BBO crystals are coated with a special “p-coating”— a layer that protects the crystal surface from degradation due to environmental effects. No sealed housing unit is required, greatly reducing cost and extra optics in the OPO beam path. The simple cavity design requires very little maintenance. Because the Scan series is so simple to operate, training at installation is typically sufficient for customers with no laser experience to operate and maintain the Scan series OPOs.

premiScan OPO Series – Premium nanosecond OPOs

The premiScan OPO series is the pinnacle of compact OPO design. This best-in-class OPO delivers the highest efficiencies and beam quality throughout the entire tuning range. By using a seamless two-crystal swapping design, the premiScan optimizes the efficiencies at the wings without compromising performance in the center of the range. And, when coupled with the uvScan doubler, the premiScan offers the widest single scan range.

The premiScan OPO comes standard with either broadband (BB), high energy broadband (HE), or midband (MB) options and is also available with an ultra low divergence option (ULD) that delivers a low divergence round beam from the OPO. The premiScan is also standard with built-in separation optics to separate signal from idler. Other options include motor driven automation with ScanMaster 3.2 software and an external lambdaScan wavemeter. Pump energies as high as 650 mJ can be used allowing the OPO to be pumped by the Quanta-Ray Lab and Pro Nd:YAG lasers.
