versaScan L-532
GREEN-PUMPED NANOSECOND OPOs
The Spectra-Physics versaScan L-532 series of 532 nm pumped OPOs are a versatile family
of OPOs specifically designed to deliver high energies in the near IR region. This OPO family
is well suited for biological applications such as photoacoustic imaging and other
applications requiring high energies in the hemoglobin absorption regions.
The versaScan L-532 series OPOs are based on the Spectra-Physics Scan Series OPO
designs. Broadband (BB), high energy double pumped (BB-HE), and midband (MB) models
are available. Optional internal separation optics separate the signal wave from the idler
wave. The OPOs can be automated through the use of a motorization option controlled by
ScanMaster software.The MB models can be doubled with uvScan.
The versaScan L-532 Advantage
• 532 nm pumped for high energies in the near IR
The OPOs are tailored for the long pulses of the Spectra-Physics Quanta-Ray® lasers to
deliver the highest efficiencies at the lowest fluences. Any Quanta-Ray laser can be used as
a pump for this family of OPOs, up to an industry leading 800 mJ at 532 nm, delivering the
highest energy OPO output available. The MB version offers tunability to below 660 nm,
making it the bluest green-pumped OPO on the market thus providing greater access to
hemoglobin dye tags.
• Both broadband and midband options available
• ScanMaster software for intuitive GUI interface
• Low pump fluences for rugged OPO performance
• P-coated crystals for longer BBO lifetimes
• Compatible with Quanta-Ray® INDI, Lab, and Pro Nd:YAG lasers
A P P L I C AT I O N S
The versaScan L-532 OPO series offers the lowest pump thresholds on the market making
them the most efficient and robust OPOs available. Lower pump fluences result in longer
lifetimes of the internal components, especially the BBO crystal. In addition, the BBO
crystals are coated with a special “p-coating” – a layer that protects the crystal surface
from degradation due to environmental effects. Because the versaScan L-532 OPO is simple
to operate, training at installation is typically sufficient for customers with no laser
experience to operate and maintain the OPO.
