Newport Unveils Highest Peak Power Laser for Biological Imaging

Newport Corporation’s Spectra-Physics Lasers Division today introduced its newest tunable ultrafast Ti:sapphire laser for high-resolution biological imaging – the Mai Tai® eHP DeepSee™. The new laser offers 65% higher peak power than the closest competitive system. As a result, this new ultrafast laser, with its integrated dispersion compensation, is ideal for nonlinearly excited fluorescence applications – including multiphoton microscopy.

“The new Mai Tai eHP DeepSee laser is an exciting solution because its pulse width has been optimized to 70 femtoseconds – taking full advantage of the system’s integrated dispersion compensation capabilities,” said Philip G. Smith, Ph.D., Product Manager for Newport’s Spectra-Physics Lasers Division, “High peak power is critical to biologists and scientists because it helps to maximize sample fluorescence and tissue penetration depth in biological imaging. By combining the industry’s highest peak power with a fully-automated and user-friendly design, integrated dispersion compensation, and the best beam pointing stability over its performance range, we believe that our new Mai Tai eHP DeepSee laser is the leading solution for demanding nonlinear fluorescence applications such as multiphoton microscopy.”

The new Spectra-Physics Mai Tai eHP DeepSee laser features full automation and computer control in a compact package. The built-in dispersion compensation capability features a large dynamic range at all wavelengths of the laser’s tuning range. It can counterbalance dispersive pulse broadening in all commonly used objectives and optical systems – thus delivering the laser’s short pulses directly to the sample for maximum fluorescence generation. This large dynamic range also enables remote adjustment of the pulse width upwards of 70 femtoseconds, should that be an application requirement.

The new Mai Tai eHP DeepSee laser is based on proven technology: With the industry’s largest installed base, the Spectra-Physics Mai Tai series of ultrafast lasers has set the standard in performance and reliability.
