1.1.1. Mai Tai Laser
The Mai Tai® Ti:Sapphire oscillator is used for a variety of applications ranging from general spectroscopy to multiphoton microscopy. With its leading performance specifications and largest installed base of any laser of its type, the Mai Tai is truly a cutting-edge tool for basic research and biological imaging.
The Mai Tai® SP ultrafast laser is the ultimate short-pulse oscillator with an unprecedented level of automation and long-term environmental stability. Designed for seeding ultrafast amplifiers, it is capable of producing a broad range of output bandwidths: 60 nm to 10 nm, corresponding to near transform-limited pulse widths from <25 fs to 100 fs. The bandwidth is user-adjustable via the graphical user interface (GUI). This unique feature allows for seeding sub-35 fs, 120 fs, and 2 ps amplifier systems using the same seed laser without manual realignment.
- Unsurpassed stability over ±10ºC operating environment
- Fully automated for hands-free operation

- DeltaFlex TCSPC Lifetime Fluorimeter
The DeltaFlex time correlated single photon counting (TCSPC) system is one of Horiba’s Delta series of next generation time correlated single photon counting lifetime instrumentation. The DeltaFlex offers the ultimate in flexibility.
This system is designed for the measurement of luminescence lifetimes ranging over 11 orders of magnitude, without the need to change cables or cards. The heart of the system is the DeltaHub timing electronics, which offers nearly lossless counting and allows for the measurement of lifetimes from 25ps to 1 second. Comprised of our high repetition rate sources, high speed detectors and ultra-low deadtime electronics, the DeltaFlex enables fast and efficient acquisition of lifetime data.
The new F-Link bus brings simplicity to modularity. Simply add any component to the instrument and the system automatically detects the new addition making it accessible from the software.
- Measure lifetimes from 25ps with Mai Tai laser source and PPD detection module
- Up to 1,000 TCSPC measurements per second – ideal for kinetics studies
- Monochromator wavelength selection
- Easy to add accessories with F-Link bus
- Comprehensive software package
- Measurement modes
- Lifetime – measure 50 ps to 1s
- Kinetic TCSPC – 1 to 10 000 decays measured sequentially in 1ms to 1min per decay
- Anisotropy – reconvolution analysis to resolve shorter rotational correlation times
- Time-Resolved Emission Spectra (TRES) – Collect up to 100 wavelength dependent decays
- Steady-State
| Minimum Lifetime | 50ps |
| Shortest measurement time | 1 millisecond |
| Repetition rates | 80 MHz (adjustable from the RF in the Harmonic Generation Module) |
| Prompt FWHM | 80-100ps |
| Deadtime | 10ns |
