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. 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® Ace™ ultrafast amplifier system.
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.

1. Due to our continuous product improvement program, specifications may change without notice.
2. Specification applies to 800 nm only.
3. A sech2 pulse shape is used to determine the pulse width as measured with a Newport PulseScout® autocorrelator.
4. Mai Tai is also available with a fixed, factory preset wavelength within the wavelength range noted.
5. Specifications apply to operation at the wavelength noted.
6. Laser operation is specified at a nominal repetition rate of 80 MHz.
7. Specification represents rms noise measured in a 10 Hz to 10 MHz bandwidth.
8. Percent power drift in any 2-hour period with <±1°C temperature change after a 1-hour warm up.
9. Avoid obstructing the air exhaust grills which will result in the recirculation of hot exhaust air. Cooling air enters through the front panel and exits through the rear fan apertures.
10. The Mai Tai is a Class IV – High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.
