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.

basiScan OPO Series – Low cost, entry level nanosecond OPOs

The basiScan, motorized basiScan-M and high energy basiScan HE series are low cost, easy-to-use, entry level, broadband OPOs. They are suitable for most biology and chemistry applications where larger linewidths are acceptable. Options include motorized control, external separation optics to separate the signal and idler, and an external wavemeter. Pump energies as high as 280 mJ can be used allowing the OPO to be pumped by the Quanta-Ray® INDI, Lab and Pro Nd:YAG lasers.
