Footnotes:

  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.

Features

Overview

The Mai Tai® Ti:Sapphire oscillator is aproven, industry standard laser source for applications ranging from general spectroscopy to multiphoton microscopy. With a large installed base and decades of field use, the Mai Tai platform is recognized as a
mature, dependable solution for demanding research and imaging environments where stability and ease of use are critical.

Choice of Models for the Application

The Mai Tai series consists of two models differentiated by pulse width and power. The Mai Tai HP provides more than 300 nm of usable tuning range (690–1040 nm), over 2.5 W of average output power, and sub 100 fs pulse widths. For users requiring shorter pulse durations, the Mai Tai eHP offers improved temporal performance relative to the HP, while offering higher power and preserving wide tunability.

Exceptional Stability and Versatility

Mai Tai reliability is built on proven, ultra stable regenerative mode locking technology. This design enables truly hands free, drop out free wavelength tuning, allowing rapid acquisition of excitation profiles with point and click control. Integrated StabiLok® real
time monitoring further enhances long term stability by ensuring excellent beam pointing performance, minimal average power fluctuations, and elimination of wavelength drift. Together, these features make the Mai Tai oscillator a highly reliable, low maintenance ultrafast laser source for everyday laboratory operation.

For users requiring access to longer wavelengths beyond 1040 nm, Spectra Physics offers the InSight® X3™, providing an exceptionally broad tuning range from 680 to 1300 nm. In addition, for microscopy applications, the Mai Tai platform is available with DeepSee™ dispersion precompensation, enabling short pulses at the sample by compensating for dispersion introduced by microscope optics.

Compatible Power Sensors

To verify and analyze the output power of your Mai Tai laser, we recommend the Ophir 3A (7Z02621) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the ophiropt.com website.  Other Ophir sensors and meters may also be suitable for the Mai Tai, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
