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. versaScan L-532 Performance Efficiency • Photo-acoustic imaging • Medical and biological processes Efficiency (%) (typical) • Vibrational spectroscopy 200 Versascan L-532/MB Versascan L-532/BB/HE Versascan L-532/BB 25 • Remote sensing • LIDAR Linewidth 30 20 15 10 Typical for Pump Laser Pulse Lenght: 7 ns Versascan L-532/BB Versascan L-532/MB 175 Linewidth (cm-1) (typical) • Highest efficiencies for hemoglobin absorption wavelengths 150 For versaScan L-532/BB/HE add 10% to the linewidth of the versaScan L-532/BB 125 100 75 50 5 1064 nm 25 0 0 650 800 1200 Wavelength (nm) 1600 2000 2400 670 800 1200 Wavelength (nm) 1600 2000 2400
