A Newport Corporation Brand

nnnn

The Spectra-Physics® alphaScan™ system is an integrated optical parametric oscillator (0P0)

nnnn

and Nd:YAG pump laser specifically designed to deliver high energies in the near IR region.

nnnn

This system is well suited for biological applications such as photoacoustic imaging and

nnnn

other applications requiring high energies in the hemoglobin absorption regions.

nnnn

With a rapid scan option, the system is capable of tuning up to 100 nm between alternating

nnnn

pulses. This allows for rapidly making differential measurements or simultaneous detection

nnnn

of markers.

nnnn

The alphaScan system is based on the Spectra-Physics Scan Series OPOs and Quanta-Ray®

nnnn

INDI Nd:YAG laser. Broadband (BB), high energy double pumped (BB-HE), and midband (MB]

nnnn

models are available. The alphaScan contains an internal filter to separate the signal from

nnnn

the idler wave. The system is software controlled and fully automated for simple operation

nnnn

through the use of a motorization option controlled by ScanMaster software.

nnnn

The integrated alphaScan system delivers the high reliability inherent in all Spectra-Physics

nnnn

lasers in a single compact, easy-to-use device. For example, lower pump fluences result in

nnnn

longer lifetimes of the internal components, especially the BBO crystal. In addition, the BBO

nnnn

crystals are coated with a special "p-coating" - a layer that protects the crystal surface from

nnnn

degradation due to environmental effects. No sealed housing is required, greatly reducing

nnnn

complexity and the number of optics in the 0P0 beam path. The simple design requires very

nnnn

little maintenance. Because the alphaScan system is simple to operate, training at

nnnn

nstallation is typically sufficient for customers with no laser experience to operate and

nnnn

maintain the 0P0.
