The Mai Tai® ultrafast laser series includes four models of increasing power, pulse width and tuning range to allow customers to choose the system to best match their application. Ideal for multiphoton microscopy, the Mai Tai HP with integrated Spectra-Physics 14 W Millennia® pump laser provides 350 nm (690-1040 nm) in useable tuning range with over 2.5 W of average power and a pulse width of less than 100 fs. This combination provides the highest peak power in the industry. For customers interested in systems with shorter pulse width, the Mai Tai BB and Mai Tai XF, both with integrated 10 W Millennia pump lasers, provide more than 240 nm in useable tuning range with a pulse width of less than 80 fs. Both are excellent choices for customers with a limited budget. Finally, the Mai Tai XF-1 with an integrated 5 W Millennia pump laser provides more than 200 nm in useable tuning range with an even shorter pulse width of less than 70 fs – an ideal choice for pumping the Spectra-Physics Spitfire® Pro ultrafast amplifier system.
The Mai Tai DeepSee™ laser with automated dispersion compensation meets all existing specifications outlined for the highly successful Mai Tai HP, but sets the new performance standards for highest peak power at the sample. Whenever ultrafast laser pulses are transmitted through optical materials, such as windows, lenses, and non-linear crystals, the added dispersion causes the pulse width to lengthen. This pulse lengthening has a negative affect on the fluorescence signal obtained. The Mai Tai DeepSee laser introduces pre-compensation which corrects in advance for the dispersion of the optical setup allowing the maximum fluorescence signals to be observed. Whenever the average power cannot be increased to prevent damaging the sample, delivering the shortest possible pulse (and therefore the highest peak power) to the sample is the only way to increase the fluorescence.
The Mai Tai laser reliability is maintained using the ultra-stable regenerative mode locking technique. Using this method, the Mai Tai laser is capable of hands-free, dropout free wavelength tuning, enabling quick collection of excitation profiles all at the click of a mouse. In addition, the Mai Tai laser includes StabiLok® technology that provides real-time monitoring of the laser system and helps maintain beam position, average power, and wavelength – making the Mai Tai laser the most reliable and most versatile hands-free laser source available.
