The Mai Tai® DeepSee™ laser with patented automated dispersion compensation meets all existing specifications outlined for the highly successful Mai Tai HP, but delivers the highest peak power all the way to 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. In addition, the Mai Tai eHP DeepSee offers the industry leading specification for peak power at 425 kW.
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. Measured after external pulse compression, or measured at the sample on a system configured with the DeepSee.
10. For optional range down to 0 fs2, contact Spectra-Physics.
11. 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.
12. The Mai Tai DeepSee 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.
