nnnnA Newport Corporation Brand
nnnnThe Spectra-Physics® alphaScan™ system is an integrated optical parametric oscillator (0P0)
nnnnand Nd:YAG pump laser specifically designed to deliver high energies in the near IR region.
nnnnThis system is well suited for biological applications such as photoacoustic imaging and
nnnnother applications requiring high energies in the hemoglobin absorption regions.
nnnnWith a rapid scan option, the system is capable of tuning up to 100 nm between alternating
nnnnpulses. This allows for rapidly making differential measurements or simultaneous detection
nnnnof markers.
nnnnThe alphaScan system is based on the Spectra-Physics Scan Series OPOs and Quanta-Ray®
nnnnINDI Nd:YAG laser. Broadband (BB), high energy double pumped (BB-HE), and midband (MB]
nnnnmodels are available. The alphaScan contains an internal filter to separate the signal from
nnnnthe idler wave. The system is software controlled and fully automated for simple operation
nnnnthrough the use of a motorization option controlled by ScanMaster software.
nnnnThe integrated alphaScan system delivers the high reliability inherent in all Spectra-Physics
nnnnlasers in a single compact, easy-to-use device. For example, lower pump fluences result in
nnnnlonger lifetimes of the internal components, especially the BBO crystal. In addition, the BBO
nnnncrystals are coated with a special "p-coating" - a layer that protects the crystal surface from
nnnndegradation due to environmental effects. No sealed housing is required, greatly reducing
nnnncomplexity and the number of optics in the 0P0 beam path. The simple design requires very
nnnnlittle maintenance. Because the alphaScan system is simple to operate, training at
nnnnnstallation is typically sufficient for customers with no laser experience to operate and
nnnnmaintain the 0P0.
